Front

What is the median?

Back

The number in the middle when the numbers are in order from least to greatest.

Front

What is the range?

Back

The difference between the largest and smallest number.

Front

What is the mean?

Front

How do you find the median of the numbers 3, 1, 4, 2, 5?

Back

Order the numbers: 1, 2, 3, 4, 5. The median is 3.

Front

How do you calculate the range of the numbers 10, 15, 20, 5?

Back

Range = Largest number - Smallest number = 20 - 5 = 15.

Front

Find the mean of these numbers: 4, 8, 6, 10.

Back

Mean = (4 + 8 + 6 + 10) / 4 = 7.

Front

Find the mode of these numbers: 1, 2, 2, 3, 4, 4, 4, 5.

Back

Mode = 4 (it appears most often).

Front

What is the first step to find the median?

Back

Order the numbers from least to greatest.

Front

If a set of numbers has no repeating values, what can you say about the mode?

Back

There is no mode.
