Question

Here's a box plot that summarizes the number of windows installed by each Clown, Inc. employee.
A horizontal box plot is labeled, Number of windows, and marked from 0 to 20 in increments of 1. A left whisker extends from 3 to 6. The box extends from 6 to 16 and is divided into 2 parts by a vertical line segment at 11. The right whisker extends from 16 to 19. All values estimated.
\[0\]
\[2\]
\[4\]
\[6\]
\[8\]
\[10\]
\[12\]
\[14\]
\[16\]
\[18\]
\[20\]
Which of these best describes the shape of the distribution?
Choose 1 answer:
A
Approximately symmetric
B
Not symmetric

Answer 1

A — Approximately symmetric.

Reason: Q1 = 6, median = 11, Q3 = 16 (median is centered in the box) and the whiskers (3 to 6 and 16 to 19) are equal length, so the boxplot is symmetric.
