Front

What is the mean?

Back

The mean is the average of a set of numbers, found 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.

How do you calculate the mean?

Back

To calculate the mean, find the sum of all data points and divide by the number of data points.

Front

What is the formula for finding the range?

Back

Range = Maximum value - Minimum value.

Front

How do you find the mode in a data set?

Back

Identify the number that occurs most frequently in the data set.

Front

What is the first step in calculating MAD?

Back

The first step is to find the mean of the data set.
