Study deliberately flawed pictograms and bar charts. Compare the tally sheet and frequency table with the display, then tick every mistake you can spot, and explain how you would fix each one. Built for GCSE statistics — see also the Chart Builder to draw correct charts.
This is what was collected in class. Does it match the chart?

Tick every mistake you think has been made. Some options are decoys — only tick what you can justify from the evidence.
For each real flaw in this scenario, write what should be done. Short answers are fine — wording does not need to be exact.
