Mean, Median, and Mode

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 in a set of numbers?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there are two middle numbers, add them together and divide by 2.

Front

What is the mode?

Back

The mode is the number that appears most frequently in a set of numbers.

Front

How do you calculate the range of a set of numbers?

Back

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

Front

Find the mean of the following numbers: 5, 10, 15, 20.

Back

Mean = (5 + 10 + 15 + 20) / 4 = 12.5.

Front

Find the median of the following numbers: 1, 3, 3, 6, 7, 8, 9.

Back

Median = 6 (the middle number in the ordered list).

Front

Find the mode of the following numbers: 2, 4, 4, 6, 7, 8, 8, 8.

Back

Mode = 8 (it appears most frequently).

Front

What do you do if there are two middle numbers when finding the median?

Back

Add them together and divide by 2.

Front

Find the range of the following numbers: 10, 15, 20, 25, 30.

Back

Range = 30 - 10 = 20.

Front

What is the median of the following set: 2, 4, 6, 8, 10, 12?

Back

Median = (6 + 8) / 2 = 7.
