5.3 Scatter plots
5.3.8 Using a calculator for bivariate data.
The common hand-held scientific calculator is now a very powerful tool. Most of thee have a Statistics mode for univariate data and a Regression mode for bivariate data. Unfortunately there are so many different brand names, and so many different models within each brand name, that it is not practical to give operational instructions here.
However it is very worthwhile (almost essential) for you learn how to use a calculator to determine the equation of the line of best fit, and the correlation coefficient, for data.
To learn about your calculator you can access:
- the manual of instructions belonging to the calculator;
- the brand name manufacturer's website;
- general (mathematical) websites;
- (school) mathematics textbooks.
