Birth months Imagine asking a random sample of 60 students from your school about their birth months. Draw a plausible graph of the distribution of birth months. (Hint: Should you use a bar graph or a histogram?)

Short Answer

Expert verified

Randomly 60 students are taken as a sample.

Step by step solution

01

Given information

Randomly 60 students are taken as a sample.

02

Concept

A histogram is a widely used graphing tool. It's utilised to summarise discrete or continuous data that's measured on an interval scale. It's a common method of displaying key data distribution features in a user-friendly manner.

03

Calculation

Because the months are categorical, a bar graph should be utilised (histogram requires that the variables are numerical).

The height of the bars must be equal to the number of pupils, and the width of the bars must be equal to the number of students. We expect the 60students in the sample to be evenly distributed over all months, resulting in around 6012=5students per month.

Let's say the numbers of students born in each month are distributed as follows:

Birth MonthFrequency
January5
February6
March5
April4
May5
June5
July5
August4
September5
October5
November6
December5

The corresponding bar graph is then:

Thus, a required graph is drawn.
