Bivariate distributions and their representation by scatter diagrams
What this topic asks you to be able to do
- Bivariate distributions, and how they are shown using scatter diagrams.
- Basic correlation, including what positive, negative, strong and weak correlation mean
- Lines of best fit, including fitting one by semi-averages, and finding the equation of such a straight line, written as y = mx + c
- Use of the line of best fit to predict values, and the limitations of predicting this way
