Mean, Median, Mode and Range

Front

What is the mean?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the total count of numbers.

Front

What is the median?

Back

The median is the middle value in a list of numbers sorted in ascending order. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mode?

Back

The mode is the number that appears most frequently in a data set. A set may have one mode, more than one mode, or no mode at all.

Front

What is the range?

Back

The range is the difference between the highest and lowest values in a data set.

Front

How do you find the median of a data set?

Back

To find the median, first arrange the numbers in ascending order. If the count of numbers is odd, the median is the middle number. If even, it is the average of the two middle numbers.

Front

How do you calculate the range of a data set?

Back

To calculate the range, subtract the smallest number from the largest number in the data set.

Front

What is an example of finding the mean?

Back

For the numbers 2, 4, 6, the mean is (2 + 4 + 6) / 3 = 4.

Front

What is an example of finding the median?

Back

For the numbers 3, 1, 2, the median is 2 after sorting them as 1, 2, 3.

Front

What is an example of finding the mode?

Back

In the set 1, 2, 2, 3, the mode is 2 because it appears most frequently.

Front

What is an example of finding the range?

Back

For the numbers 5, 10, 15, the range is 15 - 5 = 10.
