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

How do you find the median?

Back

To find the median, arrange the numbers in order and identify the middle number. 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.

Front

How do you calculate the range?

Back

The range is calculated by subtracting the smallest number in a data set from the largest number.

Front

Find the mean of the following numbers: 10, 20, 30, 40, 50.

Back

Mean = (10 + 20 + 30 + 40 + 50) / 5 = 30.

Front

Find the median of the following numbers: 3, 1, 4, 2, 5.

Back

Arrange in order: 1, 2, 3, 4, 5. Median = 3.

Front

Find the mode of the following numbers: 2, 3, 4, 4, 5, 5, 5, 6.

Back

Mode = 5 (it appears most frequently).

Front

What is the range of the following numbers: 8, 3, 5, 10, 2?

Back

Range = 10 - 2 = 8.

Front

If the scores are: 70, 80, 90, 100, what is the mean?

Back

Mean = (70 + 80 + 90 + 100) / 4 = 85.

Front

What is the median of the following set: 7, 9, 5, 6?

Back

Arrange in order: 5, 6, 7, 9. Median = (6 + 7) / 2 = 6.5.
