Year 12 Unit 3
Brief Description:
This statistical investigation asks students to design an electronic survey to answer questions about a problem of interest, for example the suitability of the year 12 facilities in the school. Students are required to design questions that allow for appropriate graphical and numerical techniques to be used. The survey questions should be written in a way that the results can be communicated is a systematic and concise manner however implementation of the survey is not a requirement of this investigation.
