Question

the box-and-whisker plot below represents some data set. what percentage of the data values are greater than or equal to 76?

Explanation:

Step1: Recall the properties of box - and - whisker plots

In a box - and - whisker plot, the box is divided into two parts by the median. The left part of the box represents the lower half of the data (25% - 50% of the data depending on the side), and the right part represents the upper half. The whiskers and the box together cover all the data. The value 76 is the median of the data set (the line inside the box).

Step2: Calculate the percentage of data greater than or equal to the median

By the definition of the median in a data set (for a box - and - whisker plot, the median splits the data into two equal parts), 50% of the data is greater than or equal to the median.

Answer:

50%
