What is the Median?

Back

The Median is the middle value in a data set when the numbers are arranged in order.

Front

How do you find the IQR of a data set?

To find the IQR, first find Q1 and Q3, then subtract Q1 from Q3.

Front

How do you calculate the Mean of a data set?

Back

Add all the numbers together and divide by the total count of numbers.

Front

What does it mean if a data set has more than one Mode?
