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.
