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 set of numbers.

Front

What is the range?

Back

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

Front

Calculate the mean of these numbers: 9, 8, 12, 6, 10.

Back

Mean = (9 + 8 + 12 + 6 + 10) / 5 = 9.

Front

Find the median of this list: 60, 58, 52, 48, 60, 67.

Back

Median = 59 (after arranging the numbers: 48, 52, 58, 60, 60, 67).

Front

What is the median of these numbers: 5, 22, 81, 16, 15, 22?

Back

Median = 19 (after arranging the numbers: 5, 15, 16, 22, 22, 81).

Front

What is the mode of the following numbers: 4, 1, 2, 2, 3, 4, 4?

Back

Mode = 4 (it appears most frequently).

Front

Calculate the range of Lizzy's test scores: 72, 94, 108, 60.

Back

Range = 108 - 60 = 48.

Front

If the numbers are 3, 7, 3, 9, what is the mode?

Back

Mode = 3 (it appears most frequently).
