Study and free time survey
Do you spend more time doing homework or playing video games? A lot of students think that they spend more time doing homework. But is this true? My class did a survey to check. In the survey, we asked students the number of hours they spend doing homework and playing video games every week. There are 800 students in our school. We asked all the students two questions:
How many hours do you spend doing homework every week?
How many hours do you spend playing video games every week?
We presented the data in three different charts. Here are the results.
| Homework (hours/week) | Number of students |
| 0 | 21 |
| 1-2 | 93 |
| 2-3 | 196 |
| 3-4 | 415 |
| 4 or more | 75 |
| Video games (hours/week) | Number of students |
| 0 | 37 |
