Front

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.

What is the median?

Back

The median is the middle value in a set of numbers when they are arranged in order. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is standard deviation?

What is the first step to find the median?

Back

The first step to find the median is to sort the data set from least to greatest.

Front

If a data set has the numbers 3, 7, 7, 2, 5, what is the mode?

Back

The mode is 7, as it appears most frequently.
