| Topic | Data representation |
| Type | Draw histogram from frequency table |
| Difficulty | Easy -1.8 This is a straightforward data representation task requiring only the mechanical construction of a cumulative frequency graph from a given frequency table. It involves simple arithmetic (adding frequencies cumulatively) and plotting points—pure procedural recall with no problem-solving, interpretation, or conceptual challenge beyond basic S1 content. |
