Question

interpreting a box plot
what percentage of data points do the two whiskers contain?
25%
50%
75%
30%

Explanation:

Step1: Recall box - plot properties

In a box - plot, the box represents the inter - quartile range (IQR). The IQR contains 50% of the data. The two whiskers together contain the remaining data.

Step2: Calculate the percentage of data in whiskers

Since the total percentage of data is 100%, and the box (IQR) contains 50% of the data. Then the percentage of data in the two whiskers is \(100\% - 50\%=50\%\)

Answer:

50%
