Back

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

Front

How do you find the interquartile range for a set of data?

Back

To find the interquartile range, subtract Q1 from Q3.

Front

What does a box plot represent?

Back

A box plot visually represents the distribution of a data set, showing the median, quartiles, and potential outliers.

Front

What is the lower quartile (Q1)?

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of a data set, marking the 75th percentile.

Front

What does it mean if two box plots have the same upper quartile?

Back

It means that the highest 25% of the data values in both sets are the same.

Front

How do you interpret the spread of data in box plots?

Back

The spread of data in box plots is indicated by the length of the box and the whiskers, showing the variability of the data.

Front

What is an inference in data analysis?
