Correlation Coefficient: Simple Definition, Formula, Easy Calculatio…
LINEAR CORRELATION. The purpose of a LINEAR CORRELATION ANALYSIS is to determine whether there is a relationship between two sets of variables. We may find that: 1) there is a positive correlation, 2) there is a negative correlation, or 3) there is no correlation. These relationships can be easily visualized by using SCATTER DIAGRAMS.
