Front

What is the mean of a data set?

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 calculate the median?

Back

Front

How do you find the range of the numbers 2, 9, 10, 6, 8?

Back

Range = Largest number - Smallest number = 10 - 2 = 8.

Front

Calculate the mean of the numbers 4, 5, 5, 2, 3, 3, 2, 8.

Back

Mean = (4 + 5 + 5 + 2 + 3 + 3 + 2 + 8) / 8 = 4.

Front

What is the first step in finding the median?

Back

The first step is to arrange the numbers in ascending order.

Front

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

Back

If there are no repeating numbers, the data set has no mode.
