# S4-2: Evaluate statements made by others about the findings of statistical investigations and probability activities.

Elaboration on this Achievement Objective

This means students will critically evaluate the strength of an argument proposed by others that is supported by statistical information. At Level Four students should consider features of the statistical investigation of others in weighing the strength of the findings. 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), data analysis (technology use, choice of displays) and the extent to which claims made are supported by the evidence.

Statistics

Level Four

This unit requires students to look at the reported state of bullying in New Zealand schools and to develop and administer their own surveys about bullying. They analyse their data and create a report outlining the results of their investigation.

Critically explore the validity of claims based on data. Evaluate the quality of survey items that are developed by others. Create survey items that align to a research question. Administer a survey, collate and display the data, and report findings.
