What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) in a dataset, representing the range of the middle 50% of the data.

How do you find the median of a dataset?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

How can you determine the spread of a dataset using a Box and Whisker Plot?

Back

The spread of a dataset can be determined by looking at the length of the box (IQR) and the length of the whiskers, which indicate variability.

What does a longer IQR indicate about a dataset?

Back

A longer IQR indicates greater variability in the middle 50% of the data, while a shorter IQR suggests less variability.
