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.

Front

What is the Median?

Back

The median is the middle value in a data set when the numbers are arranged in order. If there are two middle numbers, the median is the average of those two.

Quartiles are values that divide a data set into four equal parts. Q1 is the first quartile, Q2 is the median, and Q3 is the third quartile.

Front

What is Q1?

Back

Q1, or the first quartile, is the median of the lower half of a data set.

Front

What is Q3?

Back

Q3, or the third quartile, is the median of the upper half of a data set.

Front

What is the Interquartile Range (IQR)?

Back

The IQR is the difference between Q3 and Q1, representing the range of the middle 50% of the data.

Front

How do you find the Median in a data set?

Back

To find the median, first sort the data from least to greatest. Then, identify the middle number.

Front

What is an Outlier?

Back

An outlier is a value that is much less or much greater than the other values in a data set.
