Mean, Median, Mode, and Range

Front

What is the mean of a set of numbers?

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 list of numbers?

Back

To find the median, arrange the numbers in ascending 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 of a data set?

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

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

Back

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

Front

Find the mean of the following numbers: 4, 8, 6, 5, 3.

Back

Mean = (4 + 8 + 6 + 5 + 3) / 5 = 26 / 5 = 5.2.

Front

What is the median of the following numbers: 1, 3, 3, 6, 7, 8, 9?

Back

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

Front

Determine the mode of the following data set: 2, 4, 4, 6, 7, 8, 4.

Back

Mode = 4 (it appears most frequently).

Front

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

Back

Range = 30 - 10 = 20.

Front

What is the median of the following numbers: 12, 15, 14, 10, 13?

Back

Median = 13 (after arranging: 10, 12, 13, 14, 15).

Front

Find the mode of this data set: 1, 2, 2, 3, 3, 4, 4, 4.

Back

Mode = 4 (it appears most frequently).
