Non-Sampling Errors as they Apply to Polls & Surveys and Experiments & Observational Studies

This workshop outlines a possible teaching unit for standard AS 3.12. The content includes strategies for developing students’ statistical literacy skills, ideas for sourcing media articles, non-sampling errors and potential biases with examples from the media, the methodologies used by polling companies, and a comparison of observational and experimental studies.  The accompanying resource pack includes articles, templates, worry questions and PowerPoints.  The unit was prepared by Dru Rose, and Experiments and Observational studies prepared by Rachel Passmore.
