Pie chart

Pie charts are specific types of data presentation where the data is represented in the form of a circle. In a pie chart, a circle is divided into various sections or segments such that each sector or segment represents a certain proportion or percentage of the total.

In such a diagram, the total of all the given items is equated to 360 degrees and the degrees of angles, representing different items, are calculated proportionately. The entire diagram looks like a pie and its components resemble slices cut from a pie. The pie chart is used to show the break-up of one continuous variable into its component parts.

The chart above shows the distribution of the number of students for different race.

Looking at the chart above, we can infer that Caucasian race have 31.15 % of the total number of students surveyed, Hispanic have 24.59%, African American have 19.67% , Asian have 16.39% and Native American have 8.20% of the total number of students surveyed.

ii)

Bar Graph

Looking at the chart above, we can infer that the highest number of student belongs to Not religious while lowest number of student belongs to Christian. And 18 students belongs to Muslim, 19 students belongs to Buddhist and 20 students belongs to Catholics.
