Task goals

  • Classify variables as qualitative or quantitative based on whether they describe categories or measurable quantities.
  • Distinguish discrete from continuous quantitative data by identifying whether values can take any value in a range or only specific isolated values.
  • Identify whether a data collection method yields primary data (collected directly by the investigator) or secondary data (obtained from existing sources).
  • Apply data classification to real-world contexts to inform choices about appropriate data collection methods and statistical analysis techniques.
