| Type | Draw histogram from frequency table |
| Difficulty | Easy -1.3 This is a straightforward histogram construction from a frequency table with unequal class widths. Students must calculate frequency densities (frequency รท class width) and draw bars with correct heights. It's a standard S1 skill requiring only routine application of the histogram formula, making it easier than average A-level questions. |
| Spec | 2.02b Histogram: area represents frequency |
| Time (mins) | \(90 - 139\) | \(140 - 149\) | \(150 - 159\) | \(160 - 169\) | \(170 - 179\) | \(180 - 229\) |
| No. of days | 8 | 10 | 10 | 4 | 4 | 4 |
