Avoiding Common Statistical Mistakes

Staying Sharp with Stats

Statistics can be tricky! Avoiding common mistakes ensures your conclusions are reliable.

Watch Out For

  • Confusing correlation with causation (just because two things happen together doesn’t mean one causes the other!).
  • Ignoring sample size—a small sample might not represent the whole group.
  • Misusing averages or graphs, which can hide important details.

Smart Stat Habits

  • Double-check your data and calculations.
  • Ask if your sample is fair and big enough.
  • Use the right type of graph or summary for your data.

Examples

  • Noticing that ice cream sales and sunburns both rise in summer, but one doesn’t cause the other.

  • Realizing a survey of just five people can’t represent a whole school.
