v1 mapping, pending teacher review. Only AQA and Edexcel are mapped so far. The first 3 pilot worksheets and their worked answers are available; remaining worksheets are coming soon. All videos are still coming soon.

Retrieval: Running totals and upper class boundaries
Fluency: Estimate medians, quartiles and counts
Reasoning: Compare both typical value and spread with evidence.
Application: Estimate how many values exceed a threshold
Common misconception: Histogram area represents frequency when widths differ.

Video brief
