Body Measurement Correlations

Ever heard of the idea that you can tell how tall a person is from the size of their stride, or that a persons height is 3.5 times the distance around their head? True or just lies? How can we tell if these relationships exist?

Examining whether two variables change together in some predicatable way is called A BIVARIATE STATISTICAL ANALYSIS. Bivariate means two things vary (change).

Bivariate statistical analysis is used regularly in science, economics, business, medical research, social science. Governments use it to plan for the future, businesses use it to see how their business is going. Put simply its used all over the place in the real world (so I don't want to hear you say "where will I ever uswe this?").

The first part of a bivariate statistical analysis is to draw a scatter plot.
