Summary: AS91035 Multivariate Data 4 Credit Internal Assessment

Plan & conduct surveys & experiments

Determine variables, clean data, display data (box & whisker graphs), compare data sets with measures of centre & spread & proportion, report findings.

Justify variables used, manage variation, justify findings.

  • Plan and conduct surveys and experiments using the statistical enquiry cycle:
    • determining appropriate variables
    • cleaning data
    • using multiple displays, and re-categorising data to find patterns, variations, in multivariate data sets
    • comparing sample distributions visually, using measures of centre, spread, and proportion
    • presenting a report of findings.
  • Plan and conduct investigations using the statistical enquiry cycle:
    • justifying the variables used
    • identifying and communicating features in context (differences within and between distributions), using multiple displays
    • making informal inferences about populations from sample data
    • justifying findings, using displays and measures.
