Click Continue, then press OK. The following pie chart will automatically appear:
From the chart we can see that 5 people are from Indiana (blue), 3 are from Kentucky (red), and 7 are from Ohio (green). The table above the pie chart also shows these numbers in percentage forms:
- 33.3% of people are from Indiana
- 20.0% of people are from Kentucky
- 46.7% of people are from Ohio
The pie chart helps us easily see that nearly half of the people in the dataset are from Ohio, as nearly half of the entire chart is green.
