Statistics Practice Tests
Five fresh practice tests following the same assessment shape: vocabulary, data type classification, summary statistics, dot plots, stem-and-leaf plots, comparing displays, and critiquing a misleading graph.
Assessment Shape
Each version is self-checking. Construction questions are checked from frequencies or leaves, so students still need to build the display rather than just recognise an answer.
| Question | Skill | Marks |
|---|---|---|
| 1 | Vocabulary | 5 |
| 2 | Data types | 3 |
| 3 | Mean, median, mode, range | 8 |
| 4-5 | Construct and choose displays | 16 |
| 6-7 | Compare and critique displays | 8 |
Skill Map
This is the concept map behind the five original tests. The source test was used only to identify what needs to be taught.
