These are transport categories for one survey. Choose a suitable diagram, sketch it, and explain why a frequency polygon is unsuitable.

Choose and draw a diagram to show how these temperatures change over time.

Eight observations each pair a sensor setting x with a response y. Choose a diagram to investigate association, and sketch it.

Choose a display that compares these two small sets of times while preserving every exact value. Construct it with keys.

The completion times are grouped into equal-width numerical intervals. Draw a suitable display for the distribution shape and name one piece of information it cannot recover.

A survey splits 90 pupils among clubs A, B, C with counts 15, 30, 45. A pie chart will show parts of the whole. Find all sector angles and explain why a mean club label is meaningless.

The bars compare two counts. Explain how the vertical scale exaggerates their difference, give the actual difference, and redraw with a zero baseline.

A survey splits 60 pupils among clubs A, B, C with counts 10, 20, 30. A pie chart will show parts of the whole. Find all sector angles and explain why a mean club label is meaningless.

The bars compare two counts. Explain how the vertical scale exaggerates their difference, give the actual difference, and redraw with a zero baseline.

Separate surveys found 12 approvals out of 20 for design A and 18 out of 40 for design B. A poster uses the approval counts to claim B has the higher approval rate. Design a fair display and evaluate the claim and its limits.
