Question

To create a boxplot for the distribution of data on the previous page, quartiles on the number line. Then draw a box above the number line side of the box at Q1 and the right side of the box at Q3. Draw box at Q2.

Explanation / Answer

Answer to question# 2)

For first graph:

First part – 6 dots

Second part – 6 dots

Third part – 6 dots

Fourth part – 6 dots

Hence this graph has distribution divided into equal widths.

Each part has 25% of the data (6/(6+6+6+6) = 6/24 = ¼ = 0.25)

.

For second graph:

First part: 6 dots

Second part: 2 dots

Third part: 6 dots and 2

Fourth part: 10 dots

In this case the dots are not equally distribution

Percent in I part = (6/24 * 100) = 25%

Percent in II part = (2/24 * 100) = 8.33%

Percent in III part = (6/24 * 100) = 25%

Percent in IV part = (10/24 * 100) = 41.67%
