## Synopsis

Scientific method. Graphical and numerical summary of data. Principles of experimental and sampling design, data acquisition, and the presentation of data. The role of mathematical models in science by investigating the relationship between quantitative variables. Analysis of data using the inferential statistical methods of hypothesis testing and confidence intervals. Communication of scientific information.

3. Describe how statistical data is collected and analysed;
4. Use Excel to present and interpret data in numerical summaries and/or graphs;
5. Use appropriate statistical summaries to explore data;
6. Perform regression and interpret results;
7. Determine confidence intervals;
8. Conduct hypothesis testing and interpret results;
9. Make statistical decisions and communicate findings in a meaningful scientific way.
