Key learning points

Bar charts compare categories; line graphs show change over time; pie charts show parts of a whole.
Angles in a pie chart: $\frac{\text{frequency}}{\text{total}}\times360^\circ$ .
Misleading graphs often abuse truncated axes — read scales carefully.

Worked example 1 — Pie chart angle

Frequency 15 out of 60. Angle?

Working

90^\circ

Fraction of $360^\circ$ .

Worked example 2 — Bar chart

Bar reaches 12 on the frequency axis. Frequency?

Working
