What are quartiles in a box plot?

Back

Quartiles are values that divide the dataset into four equal parts: Q1 (25th percentile), median (50th percentile), and Q3 (75th percentile).

How is the interquartile range (IQR) calculated?

Back

The interquartile range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

What does the whisker in a box plot represent?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the range of the data.

How can you identify outliers in a box plot?

Back

Outliers can be identified as points that fall outside the whiskers, typically defined as 1.5 times the IQR above Q3 or below Q1.

What does a wider box in a box plot indicate?

Back

A wider box indicates a larger interquartile range (IQR), suggesting greater variability in the middle 50% of the data.
