Scatter Graphs

Overview

The programme looks at how scientists collect data and analyse relationships using scatter graphs. Presenters Jamie and Katie discover how these research techniques can be used to investigate the size of black cab drivers' brains, marathon runners' times and the causes of acne. Within these contexts we see how to plot scatter graphs, draw lines of best fit and describe types of correlation using real data.

The programme aims to present the topic of scatter graphs in a lively, interesting and entertaining style. The content is linked throughout to the requirements of GCSE Intermediate Mathematics. It includes tips for answering examination questions and a discussion of a typical exam error in the 'Tick or Trash' section. Emphasis is placed on achieving a good line of best fit and describing the type of correlation. Relationships between sets of data are analysed and we see how to use the graphs to make predictions. Clear graphic and visual explanations are used to demonstrate the techniques covered. The programme uses real research data to build an understanding of the principles of correlation. The content is chosen to engage the student audience, as well as to support teachers by bringing the outside world into the classroom.
