Students should be able to:

•Use the statistical enquiry cycle and elementary principles of experimental design, surveys and polls, including potential sources of bias
•Interpret statistical inferences
•Interpret a wide variety of statistical tables and graphs
•Analyse a wide variety of statistical situations
•Critique causal relationship claims and interpret margins of error
The approach used in interpreting the margins of error is new and is based on making informed approximations or rules of thumb to interpret reported margins of error (linked to confidence intervals).

A: critiquing causal-relationship claims
-Identifies the type of study, that is, survey, poll, experiment or observational study.
-Draws on understandings of statistical investigations, and how the different types of studies are conducted, uses “critical questions” to evaluate the study, makes a judgement about the claim and justifies.

B: interpreting margins of error.
-The approach here is new to the Statistics curriculum, and is based on making informed approximations or rules of thumb to interpret reported margins of error and be linked to confidence intervals.
-Explains the connections among sample, population, sampling variability, sample size, confidence level and poll percentages in relation to the reported margin of error.
-Estimates the margin of error for subgroups of the poll percentages.
