Samaira and Kabir decided to act like reporters and collect information from their friends about how many hours a day they spend watching TV. They collected data from 35 friends and recorded it in a notebook.
The collected data can be organized into a frequency table to make it easier to understand:
| No. of Hours Spent Watching TV | No. of Children |
|---|---|
| $\frac{1}{2}$ hour | 10 |
| $1$ hour | 9 |
| $1\frac{1}{2}$ hours | 8 |
| $2$ hours | 4 |
| More than $2$ hours | 4 |
Questions for Analysis:
Joseph Uncle takes stock of the play items (toys, board games, and sports items) in his store. He uses a pictograph to record the items. Since there are too many items, his helper Dipesh suggested using a scale where one picture (icon) represents multiple items.
| Name of the Item | Number of Icons | Total Quantity (Icons $\times$ 5) |
|---|---|---|
| Toys | 8 icons | $8 \times 5 = 40$ toys |
| Board games | 9 icons | $9 \times 5 = 45$ board games |
| Sports items | 11 icons | $11 \times 5 = 55$ sports items |

| Monday | 9 icons | $9 \times 3 = 27$ |
