Chapter 2: Q. 58 (page 135)

Describe the shape of this distribution.

Short Answer

Expert verified

The distribution is approximately symmetrical.

Step by step solution

01

Content Introduction

The number of peaks in distribution, as well as its symmetry, skewness, and uniformity, are used to describe its shape. In skewed distributions, more points are plotted on one side of the graph than the other.

02

Content Explanation

Looking at the shape of the given histogram, we clearly say that the values are peaked at the centre and the left side of the histogram is almost the same as the right side of the histogram.

Thus, the shape of the distribution is symmetrical.
