💡 Exam Tips for Bar Charts & Pictograms

Bar Charts:

  • Equal bar widths: All bars must be the same width
  • Equal spacing: Gaps between bars should be consistent
  • Start at zero: Y-axis must start at zero to avoid misleading comparisons
  • Label everything: Title, axis labels, and scale markings
  • Use a ruler: Draw straight, neat lines
  • Check scale: Make sure your scale allows all data to fit

Pictograms:

  • Choose appropriate scale: Avoid too many or too few symbols
  • Partial symbols: Be precise with halves, thirds, quarters
  • Alignment: Keep symbols in neat rows
  • Clear key: Always state what each symbol represents
  • Consistent size: All symbols must be identical in size
  • Reading carefully: Pay attention to partial symbols when counting
