Basic Statistics & Probability Scatter Plots & Correlation
Correlation. With scatter plots we often talk about how the variables relate to each other. This is called correlation. There are three types of correlation: positive, negative, and none (no correlation). Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one's height increases so does the
