Question

The following box and whiskers plot represents the height of ten different plants:

About what percentage of plants has a height greater than 6 cm?

• A. $25\%$
• B. $50\%$
• C. $75\%$
• D. $100\%$

Answer 1

The correct option is C $75\%$

A box and whiskers plot is constructed from five values: minimum number, lower quartile, median, upper quartile, and maximum number.

Each section of the Box and Whiskers plot contains approximately 25% of the data for that set.


Since, the lower quartile of the given data is 6 cm, so about $25\%+25\%+25\%=75\%$ of the plants has a height greater than 6 cm.
