Question

The histogram below represents the number of points Mandy scored per game. The graph makes the data appear symmetric when it is actually skewed.

How can the graph be adjusted to show the skew?

A) The intervals on the x-axis can be changed to be continuous and consistent.

B) The interval on the y-axis can be changed to show only the relevant numbers, 3 and 5.

C) The scale on the x-axis can be increased to show the interval 25–29.

D) The scale on the y-axis can be decreased to show only the numbers 0–5.

Answer 1

A) The intervals on the x-axis can be changed to be continuous and consistent

Answer 2

Option A is right

Explanation:

Given is a histogram that represents the number of points Mandy scored per game.

The graph shows on x axis

0-4, 5-9, 10-14, 20-24

We find that between 4 and 5 gap is there

Also 15-19 is not shown at all

To make this perfect the class intervals should be made as

-0.5-4.5, 4.5-9.5, 9.5 - 14.5, 14.5-19.5, 19.5-24,5

Then the histogram would give an idea about symmetry or skewness

Hence option A) The intervals on the x-axis can be changed to be continuous and consistent.
