What is the Mean?
The mean is the average of a set of numbers.
It is found by adding up the set of numbers and then dividing the total by the number of data points in the set.
How to find the mean
Step 1) Add up all the numbers in the set.
Step 2) Divide the total by the total number of data points in the set.
Example 1) Find the mean of 5, 7, 8 and 4
Step 1) Add up the numbers to give a total of 5+7+8+4=24
Step 2) Divide the total by the number of data points. 24 ÷ 4 = 6
Answer: the mean is 6.
Example 2) Find the mean of 8, 2, 5, 7 and 13
Step 1) Add up the numbers to give a total of 8+2+5+7+13=35
Step 2) Divide by the number of data points. 35 ÷ 5 = 7
Answer: the mean is 7.
What is the Median?
The median is the midpoint (or middle value) of a set of numbers.
It is found by ordering the set of numbers and then finding the middle value in the set.
How to find the median
Step 1) Order the numbers in the set from smallest to largest.
Step 2) Find the middle number.
- If there is an odd number of values in the set, then the median is the middle value.
- If there is an even number of values in the set, then the median is the average of the two middle values.
Example 1) Find the median of 5, 7, 8, 2 and 4
Step 1) Put the numbers in order: 2, 4, 5, 7, 8
Step 2) There is an odd number of values in the set so the median is the middle value which is 5.
Answer: the median is 5.
Example 2) Find the median of 23, 27, 16, 31
Step 1) Put the numbers in order: 16, 23, 27, 31
Step 2) There is an even number of values in the set, so the median is the average of the middle two values.
(23+27) ÷ 2 = 25
Answer: the mean is 25
Example 3) Find the median of 7, -4, 9, -7, -2, 5
Step 1) Order the numbers: -7, -4, -2, 5, 7, 9
To get the average, simply add the two values together and divide by 2:
(-2 + 5) ÷ 2 = 1.5
Answer: the mean is 1.5
What is the Mode?
The mode is the most common (or the data point that appears most often) in a set of data.
It can be found by putting the data into an ordered list and seeing which data point occurs most often.
How to find the mode
Step 1) Put the data into an ordered list.
Step 2) Check that you have got the same number of data points.
Step 3) The mode is the data point which is the most common.
Finding the Mode Examples
Example 1) Find the mode of 3, 6, 4, 3, 2, 4, 7, 8, 6, 3, 9
This gives us: 2, 3, 3, 3, 4, 4, 6, 6, 7, 8, 9
Step 2) Check the number of data points in both lists is the same.
Both lists have 11 data points.
Step 3) The mode is the number which occurs most often.
Answer: the mode is 3.
Example 2) Find the mode of 0.6, 0.3, 0.4, 0.2, 0.4, 0.7, 0.6, 0.1, 0.4, 0.9
This gives us: 0.1, 0.2, 0.3, 0.4, 0.4, 0.4, 0.6, 0.6, 0.7, 0.9
Both lists have 10 data points.
Answer: the mode is 0.4.
Back to Top
What is the Range?
The range is the gap between the smallest and largest data point.
It is found by putting the data into an ordered list and find the difference between the largest and smallest amount.
How to find the range
Step 3) The range is the difference between the largest and smallest data point.
To find the range simply subtract the smallest number from the largest number.
Finding the Range Examples
Example 1) Find the range of 14, 21, 9, 32, 27, 15, 12, 30
This gives us: 9, 12, 14, 15, 21, 27, 30, 32
Both lists have 8 data points.
Step 3) The range is the difference or gap between the largest and smallest numbers.
Answer: the range is 32-9=23.
Example 2) Find the range of 6, 2, -7, 2, -5, 11, 3, -4, 0, 9
This gives us: -7, -5, -4, 0, 2, 2, 3, 6, 9, 11
Answer: the range is 11-(-7)=18.

Mean Median Mode Questions and Answers
1. Find the mean of the first 10 odd integers.
First 10 odd integers: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
Mean = Sum of the first 10 odd integers/Number of such integers
= (1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19)/10
Therefore, the mean of the first 10 odd integers is 10.
2. What is the median of the following data set?
32, 6, 21, 10, 8, 11, 12, 36, 17, 16, 15, 18, 40, 24, 21, 23, 24, 24, 29, 16, 32, 31, 10, 30, 35, 32, 18, 39, 12, 20
The ascending order of the given data set is:
6, 8, 10, 10, 11, 12, 12, 15, 16, 16, 17, 18, 18, 20, 21, 21, 23, 24, 24, 24, 29, 30, 31, 32, 32, 32, 35, 36, 39, 40
Number of values in the data set = n = 30
n/2 = 30/2 = 15
15th data value = 21
(n/2) +1 = 16
16th data value = 21
= (15th data value + 16th data value)/2
= (21 + 21)/2
3. Identify the mode for the following data set:
21, 19, 62, 21, 66, 28, 66, 48, 79, 59, 28, 62, 63, 63, 48, 66, 59, 66, 94, 79, 19 94
Let us write the given data set in ascending order as follows:
19, 19, 21, 21, 28, 28, 48, 48, 59, 59, 62, 62, 63, 63, 66, 66, 66, 66, 79, 79, 94, 94
Here, we can observe that the number 66 occurred the maximum number of times.
Thus, the mode of the given data set is 66.
4. Consider the following frequency distribution. Calculate the mean weight of students.
The given distribution has discontinuous class intervals, so we need to make them continuous.
Here, ∑f i = 40 and ∑f i d i = 35
By Assumed mean method,
Mean = a + (∑f i d i /∑f i )
= 43 + (35/40)
= 43 + 0.875
Therefore, the mean weight of the students is 43.875 kg.
5. Find the mean for the following distribution.
Mean = ∑f i x i /∑f i
6. Calculate the median marks of students from the following distribution.
N/2 = 90/2 = 45
Cumulative frequency greater and nearer to 45 is 47, which lies in the interval 40 – 50
Median class is 40 – 50.
Lower limit of the median class = l = 40
Class size = h = 10
Frequency of the median class = f = 20
Cumulative frequency of the class preceding the median class = cf = 27
As we know,
Median = 40 + [(45 – 27)/20] × 10
= 40 + (18/2)
Hence, the median marks of the students = 49.
7. The given distribution shows the number of runs scored by some top batsmen of the world in one-day international cricket matches.
Find the mode of the above distribution.
From the given,
Modal class = 4000 – 5000
Lower limit of the modal class = l = 4000
Class width (h) = 1000
Frequency of the modal class = f 1 = 18,
Frequency of the class preceding the modal class = f 0 = 4
Frequency of the class succeeding the modal class = f 2 = 9
Mode = l + [(f 1 – f 0 )/ (2f 1 – f 0 – f 2 )] × h
Mode = 4000 + [(18 – 4)/(36 – 4 – 9)] × 1000
= 4000 + (14000/23)
= 4000 + 608.695
= 4608.7 (approximately)
Thus, the mode of the given data is 4608.7 runs
8. If the median of a distribution given below is 28.5, then find the value of x and y.
N/2 = 60/2 = 30
Median of the given data = 28.5
Median class is 20 – 30 with a cumulative frequency = 25 + x.
Lower limit of median class = l = 20
Cumulative frequency of the class preceding the median class = cf = 5 + x
28.5 = 20 + [(30 − 5 − x)/ 20] × 10
28.5 – 20 = (25 – x)/2
8.5 × 2 = 25 – x
17 = 25 – x
x = 25 – 17
Therefore, x = 8
60 = 5 + 20 + 15 + 5 + x + y
60 = 5 + 20 + 15 + 5 + 8 + y
y = 60 – 53
Therefore, the value of x = 8 and y = 7.
9. For a moderately skewed distribution, the mean and median are respectively 26.8 and 27.9. What is the mode of the distribution?
Mean = 26.8
Median = 27.9
Using the relationship between mean, median and mode,
Mode = 3 Median – 2 Mean
= 3 × 27.9 – 2 × 26.8
= 83.7 – 53.6
Therefore, the mode of the distribution is 30.1.
10. If the mean of the given frequency distribution is 35, then find the missing frequency y. Also, calculate the median and mode for the distribution.
Given that the mean of the distribution is 35.
So, (430 + 45y)/(14 + y) = 35
430 + 45y = (14 + y)35
430 + 45y = 490 + 35y
45y – 35y = 490 – 430
Thus, the missing frequency is 6.
Now, we can calculate the mode as follows:
Mode = 30 + [(7 – 4)/(14 – 4 – 6)] × 10
= 30 + (30/4)
Now, using the formula Mode = 3Median – 2 Mean, we can get the value of median.
37.5 = 3 Median – 2 (35)
3 Median = 37.5 + 70
Median = 107.7/3

Mean, Median, Mode and Range
The mean, the median and the mode are three different measures of average which we can use. The range is a measure of how spread out data is.
The mode is the value that appears most often.
The median is the middle number (when the numbers are in order).
To calculate the mean add up all the numbers and then divide by how many numbers there are.
The range is the difference between the biggest number and the smallest number.
Example 1: Here are a list of 7 numbers: 7 4 7 9 5 1 2 Find: a) The mode b) The median c) The mean d) The range
a) The mode is the most common number The only number that appears more than once is 7 The mode is 7
b) The median is the middle number (but only when the numbers are in order) We have to put the numbers in order: 1 2 4 5 7 7 9 We can now find the middle number:
The median is 5
c) To find the mean we need to add up all the numbers then divide by how many numbers there are:
1 + 2 + 4 + 5 + 7 + 7 + 9 ⁄ 7 = 35 ⁄ 7 = 5
The mean is 5
d) To find the range we take the smallest number away from the biggest number 9 - 1 = 8 The range is 8
Example 2: Here are a list of 8 numbers: 6 6 13 5 11 11 11 9 Find: a) The mode b) The median c) The mean d) The range
a) The mode is the most common number 11 appears three times, that is more than any other number The mode is 11
b) To find the median (the middle number) we need to put the numbers in order: 5 6 6 9 11 11 11 13
We can see that there is not one middle number, we have 9 and 11 in the middle. When this happens the median is half way between the two middle numbers, the middle of 9 and 11 is 10. We can work this out by adding 9 and 11 and then dividing by 2.
9 + 11 ⁄ 2 = 10 The median is 10
5 + 6 + 6 + 9 + 11 + 11 + 11 + 13 ⁄ 8 = 72 ⁄ 8 = 9
The mean is 9
d) To find the range we take the smallest number away from the biggest number 13 - 5 = 8 The range is 8
Calculate the mode, the median, the mean and the range:

Mean, Median, Mode
Here you will learn about the measures of central tendency, which is the mean, median and mode of data sets, including what they are and how to find them.
Students first learn about measures of central tendency in the 6 th grade and expand this knowledge as they move through middle school and high school statistics.
What is mean median mode?
The mean, median and mode are different measures of center of a numerical data set. They are a way of summarizing a data set with a single number.
The mean is the average of a numerical data set.
To calculate the mean, find the total of the values and divide the total by the number of values .
The “number of values” is sometimes referred to as the “number of numbers”.
Let’s find the mean of this data set.
The mean is 4.57 (rounded to 2 decimal places)
Step-by-step guide: Mean in math
The median is the middle number of a numerical data set.
To find the median, we need to arrange the values in numerical order, from the smallest value to the highest value, and find the middle value .
The middle value is the median value.
Let’s find the median of the same data set.
The median is 5 because it is the middle number of data points.
Step-by-step guide: Median
The mode is the most common number. To find the mode, we need to find the value in the data set that occurs the most number of times.
Let’s find the mode of the data set.
The number that occurs the most or is most frequent is 6.
The mode is 6.
Step-by-step guide: Mode in math
The range is the difference between the greatest value and the least value of a data set. It is a measure of variability not a measure of center.
Let’s find the range of the data set.
The range is 6.
Step-by-step guide: Range in math
Common Core State Standards
How does this apply to 6 th grade math?
- Grade 6 – Statistics and Probability 6.SP.A.3 Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
- Grade 6 – Statistics and Probability 6.SP.A2 Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
- Grade 6 – Statistics and Probability 6.SP.B.5c Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.

How to find the mean median mode
In order to find the mean, median or mode:
List the numbers in order from least to greatest.
To find the mean, find the total of the numbers in the data set and divide by the number of values in the data set.
- To find the median, find value(s) in the middle of the data set.
To find the mode, look for the value(s) that occur the most; there may be more than one mode.
To find the range, find the difference between the largest value and the smallest value.
Mean median mode examples
Example 1: finding the mode.
Find the mode for the given data set.
- List the numbers in order from least to greatest.
4 To find the mode, look for the value(s) that occur the most; there may be more than one mode.
7 occurs the most, so the mode is 7.
Example 2: finding the median
Find the median for the given data set.
List the numbers in order from least to greatest
To find the median, find values in the middle of the data set.
The value in the middle is 9. The median is 9.
Example 3: finding the median
Find the median of the given data set.
Find the middle of the data set. There is an even number of values, so we have a middle pair. To find the median, find the average of the two middle numbers or the midpoint of 4 and 6.
The average of 4 and 6 or the midpoint between 4 and 6 is 5. So, the median is 5.
Example 4: finding the mean
Find the mean of the given data set.
Although not necessary, it can be helpful to put the values in order.
To find mean, find the total of the numbers in the data set and divide by the number of values in the data set.
The mean is 7.6.
Example 5: finding the mean, median, and mode
Find the mean, median, and mode of the data set.
The mean is 13.
There are an even number of data points in the data set, so there are two values in the middle, 12 and 13. To find the median, find the average of the two numbers of the midpoint.
The median is 12.5.
12 is the value that occurs the most which means it is the mode.
Example 6: finding the mean, median, mode, and range
The mean is 4.875.
There are an even amount of values in the data set, 4 and 6 are in the middle. To find the median find the average of 4 and 6 or find the midpoint of 4 and 6.
The median is 5.
3 and 6 both occur twice, so there are two modes, 3 and 6. Since there are two modes, the data is bimodal.
The modes are 3 and 6.
Teaching tips for mean, median, mode
- Incorporate project based data science learning activities where students have opportunity to collect their own data, as well as do data analysis/statistical analysis on the collected data.
- Although worksheets and paper-based quizzes have their place, consider alternate forms of formative assessments that engage students to gain a global perspective by having them summarize data in real time with real world data points.
Easy mistakes to make
- Mixing up the measures of center For example, if a student is asked to find the median and they find the mean.
- Listing the numbers in descending order instead of ascending order When summarizing data, the best way to list the data is in ascending order (from least to greatest) not descending order (greatest to least).

Mean, median and mode – quick review and tutorial.
Mean, mode and median are basic statistical tools used to calculate different types of averages. Below is a quick tutorial followed by practice questions.
Mean Mean is the most common form of average used. To calculate mean, you simple add up all the values of data given and divide by the number data provided.
Example Find the mean of 8, 5, 7, 10, 15, 21 Sum of values = 8 + 5 + 7 + 10 + 15 + 21 = 66 Number of data = 6 Mean = 66/6 = 11
Median Median refers to the middle value among a set or series of values after they have been arranged in numerical order. Median thus means the middle of the set of values. When two numbers fall in the middle, you simple add the value of the two numbers and divide by 2 to get the middle of the two numbers.
Example Arrange these numbers in ascending order and then find the median First arrange in ascending order 8, 5, 7, 10, 15, 21 = 5, 7, 8, 10, 15, 21
There are 6 numbers on the series and two fall in the middle = 8 and 10 The median = 8 + 10/2 = 18/2 =9
Mode Mode refers to the most occurring number or value among a set of values. Note that it is possible not to have a most occurring number and then the answer becomes ‘No Mode’
Example 8, 5, 7, 10, 15, 21, 5, 7, 2, 5 Mode refers to the most occurring number 8, 10, 15, 2 and 21 occur once
5 occurs 3 times 7 occurs 2 times The most occurring number is 5, which occurs three times.

Common Mistakes Calculating Mean, Median, and Mode
- Calculating Mean: Not adding up all the numbers correctly and dividing by the wrong number of elements.
- Calculating Median: Ordering incorrectly; not understanding the difference between the median and the average. The median is the mid-point number, where half the elements fall above and half below. The mean (or “average”) is the sum of all data divided by the number of data points.
- Calculating the Mode: Incorrectly identifying the most frequently occurring number(s) or not understanding that a set of data may have multiple modes or no mode at all.
- Not understanding outliers: Extreme values have a huge effect on the mean, but have less impact on the median and mode.
- Not understanding the difference between sample and population: The formulas and methods used to calculate measures of central tendency can be different for sample and population.

High School Math : Understanding Mean, Median, and Mode
Study concepts, example questions & explanations for high school math, all high school math resources, example questions, example question #11 : basic statistics.
Reorder the numerals in the set, from least to greatest.
The mean is the sum of the numerals divided by the number of data points.
The mean is 15.
The range is the difference between the maximum and the minimum.
The range is 8.
Example Question #1 : Understanding Mean, Median, And Mode
For the following data set:
Which is the smallest?
None of the answers
Put the data in order from smallest to largest and then calculate each stastic: mean, mode, median, range
Example Question #1 : Data Properties
Find the median of the following number series:
3, 6, 27, 19, 8, 11, 30, 42, 7, 39
The first step to finding the median is always to put the numbers in the proper order:
3, 6, 7, 8, 11, 19, 27, 30, 39, 42
When we have an even amount of numbers, we find the average (or mean) of the middle two to get the median:
11 + 19 = 30/2 = 15
Example Question #15 : Basic Statistics
With a standard deck of playing cards, what is the probability of picking one red card followed by one black card, without replacement?
In a standard deck of playing cards we have:
Which statement is true concerning the following data set:
First, put the data in order, smallest to largest:
Note, the mode is the number most often repeated in the data set and the median is the middle number.
Example Question #2 : Understanding Mean, Median, And Mode
Alice recorded the outside temperature at noon each day for one week. These were the results.
Tuesday: 85
Wednesday: 82
Thursday: 84
Saturday: 79
What was the mean temperature for the week?
The mean is calculated by adding all the values in a group, then dividing the sum by the total number in the group.
Example Question #3 : Understanding Mean, Median, And Mode
What is the mode of the temperatures?
The mode is the number that appears most frequently in a series of numbers. First, organize the numbers in order from least to greatest. Then, identify the value that is repeated most frequently.
Example Question #4 : Understanding Mean, Median, And Mode
What is the median temperature?
The median is determined by ordering the values in the group from least to greatest and identifying the value directly in the middle. For instance, if five numbers are ordered from least to greatest, the third is the median.
Example Question #11 : Data Properties
What is the probability of rolling an odd sum less than seven when rolling two standard six-sided dice?
The odd numbers less than seven are one, three, and five.

Solution: First 10 odd integers: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 Mean = Sum of the first 10 odd integers/Number of such integers = (1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19)/10 = 100/10 = 10 Therefore, the mean of the first 10 odd integers is 10. 2. What is the median of the following data set?
Example 1: Find the mean, median, mode, and range for the following list of values. The mean is commonly known as the "average" which is calculated by getting the sum of all values in the list and then divided by the number of entries. The symbol used to represent the mean is [latex]\bar X [/latex], often read as "x-bar".

Median. The median is often referred to as "the middle", which is precisely what it is.. There are two common ways of finding the middle value(s): Method 1: Put the numbers in order from smallest to largest and find the middle value/middle two values. Cross out the smallest number and the largest number, then cross out the next smallest and largest, keeping going crossing out pairs of ...

Mean, Median and Mode Mean What is it? An (arithmetic) mean is the average of a set of n numbers. How do you find it? Add all the elements in a set. Then, divide by the number of elements. Examples: The mean of 7 and 11 is 9. 7+11 The mean of -6, -3, 2, 4, and 4 is .2 (5 elements in the set) Jim's math test scores were 78, 88, 91, and 94.
Example 4: finding the median. Find the median: Make sure the list of numbers is in numerical order. Find the middle of the data set. There is an even number of values, so we have a middle pair. The average of 4 4 and 6 6 is 5 5. (Or the midpoint of 4 4 and 6 6 is 5 5 ). \frac {4+6} {2}=\frac {10} {2}=5 24+6 = 210 = 5.
The mode is 7. b) The median is the middle number (but only when the numbers are in order) We have to put the numbers in order: 1 2 4 5 7 7 9. We can now find the middle number: The median is 5. c) To find the mean we need to add up all the numbers then divide by how many numbers there are: 1 + 2 + 4 + 5 + 7 + 7 + 9 7 = 35 7 = 5.

6. Step-by-step guide: Mode in math Range The range is the difference between the greatest value and the least value of a data set. It is a measure of variability not a measure of center. Let's find the range of the data set. 7 - 1 = 6 7 − 1 = 6 The range is 6. 6.
Example. Arrange these numbers in ascending order and then find the median. First arrange in ascending order 8, 5, 7, 10, 15, 21. = 5, 7, 8, 10, 15, 21. There are 6 numbers on the series and two fall in the middle = 8 and 10. The median = 8 + 10/2 = 18/2 =9. Mode. Mode refers to the most occurring number or value among a set of values.
