Full topic summary

Choosing and reading charts — bar charts, pie charts, line graphs — is about clear scales and what each representation emphasises.

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: frequencytotal×360∘\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∘90^\circ

Fraction of 360∘360^\circ.

Worked example 2 — Bar chart

Bar reaches 12 on the frequency axis. Frequency?

Working

1212

Read the scale.

Worked example 3 — Comparing groups

What must dual bar charts share?

Working

a common scale\text{a common scale}

Fair comparison.
