Question

a golfer recorded the score for each round of golf she played in a season. the box-and-whisker plot (sometimes called a boxplot) summarizes these scores. box-and-whisker plot image use the box-and-whisker plot to answer the following. (a) what is the median score? (b) what is the lowest score? (c) what is the first quartile (q₁) of the scores?

Explanation:

Step1: Analyze the box - and - whisker plot components

In a box - and - whisker plot, the median is represented by the line inside the box, the lowest score is the left - most point of the whisker, and the first quartile ($Q_1$) is the left - hand side of the box.

Step2: Find the median score

Looking at the box - and - whisker plot, the line inside the box (median) is at 80.

Step3: Find the lowest score

The left - most point of the whisker is at 72 (from the number line: the left whisker starts at 72).

Step4: Find the first quartile ($Q_1$)

The left - hand side of the box is at 75.

Answer:

s:
(a) The median score is 80.
(b) The lowest score is 72.
(c) The first quartile ($Q_1$) of the scores is 75.
