Pie charts are graphical representations that show how much of the whole region each population represents. The distribution frequencies can be compared for these populations.
<h3>How to interprete a pie chart?</h3>Pie charts are circular graphs that represent the total amount (100%) of something, a group, or a unit.
This chart is divided into different sectors -slices-. Each of them is a category or subgroup and reflects the frequency or the magnitude of the elements composing the whole unit.
Pie charts are useful to make comparisons and easy interpretations according to the data we are representing.
For a better, I will provide you with a hypothetical example,
Let us imagine we are studying an unknown area of Mars known as <u>Region X</u>, where there are several populations, named Population 1, population 2, population 3, population 4, population 5, population 6, population 7, and population 8.
In this study, we need to express <u>how much of the whole Region X each population represents</u>. So we will use a pie chart to make this comparison and data about the population sizes.
We will consider,
- Region X as the whole group or unit (100%)
- Each population is a sector -slice- that represents a percentage of the whole group.
You will find this pie chart in the attached files.
From this pie chart, we can conclude that,
- Population 7 is the largest, representing 27% of the whole region X.
- Population 1 is the smallest, being only 3% of region X.
- Populations 6 and 7 together represent 50% of the whole region X.
- Populations 1, 2, 3, 4, and 5 together represent the other 50% of the region X.
This is an example. Now you can use your data and make the same reasoning to answer the question.
