TLRI+2009

Material for trialling - 2009 - project supported by funding from Teaching and Learning Research Initiative (TLRI) S5-1 Plan and conduct surveys and experiments using the statistical enquiry cycle: A determining appropriate variables and measures B considering sources of variation C gathering and cleaning data D using multiple displays, and re-categorising data to find patterns, variations, relationships, and trends in multivariate data sets E comparing sample distributions visually, using measures of centre, spread, and proportion F presenting a report of findings.
