Elaboration on this Achievement Objective

This means that students will evaluate the statistical investigation or probability activity undertaken by others by considering features of the investigation. These features include the appropriateness of sampling methods (for example number, representativeness), quality of the data collection (for example questions asked, accuracy of measurement, fairness of the experiment), choices of measures (types of questions, and responses allowed), data analysis (technology use, choice of displays) and the extent to which claims made are supported by the evidence. Together these factors should be used to evaluate the investigation as a whole.
