ABSTRACT
Statistical inference allows us to draw general conclusions from the available data. Chapters 1-3 introduced data types, linear regression, and one-way ANOVA (comparison of groups) without details about statistical inference. Chapter 4 introduced the normal (Gaussian) distribution. We are now ready to combine the two parts: if the variation can be described by the normal distribution, then we can carry out proper statistical analyses; in particular, compare groups and infer about the association between two variables.
