Unit focus

  • Data collection should answer a clear question. Categorical data uses labels, while discrete numerical data uses countable numbers.
  • Use this routine: Ask question → Identify variable → Collect fairly → Tally → Frequency table → Check total.
  • Watch for question too vague: State exactly what data will answer.
