What does the lower quartile (Q1) represent?

Back

The lower quartile (Q1) represents the value below which 25% of the data falls.

Front

What does the upper quartile (Q3) represent?

Back

The upper quartile (Q3) represents the value below which 75% of the data falls.

Front

What is the median in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest.

Front

How do you find the median of an even set of numbers?

Back
