Covid-19 took the world by storm and by April 2020, large numbers of people around the world were tested positive for the virus. In the frequency distribution below, the number of people infected in 40 different countries are given.
| Hundreds of thousands of people infected | Number of countries |
| [1.0;3.0) | 5 |
| [3.0;5.0) | 8 |
| [5.0;7.0) | 17 |
| [7.0;9.0) | 6 |
| [9.0;11.0) | 3 |
| [11.0;13.0) | 1 |
| Total | 40 |
