1.11 Investigate bivariate numerical data using the statistical enquiry cycle

Internal 3 credits

This standard is derived from Achievement Objective S6.1, plan and conduct surveys and experiments using the statistical enquiry cycle.

In particular,

  • determine and justify appropriate variables and measures
  • consider sources of variation
  • gathering and cleaning data
  • using multiple displays, and re-categorising data to find patterns and relationships, in multivariate data sets
  • presenting a report of findings

The data must be numerical, with the explanatory variable (x variable) being either continuous or discrete, and the response variable (y variable) measured.  The context of the data should be considered throughout the process.
