The product moment correlation (also known as Pearson's correlation coefficient) measures the linear relationship between two variables. It ranges from -1 to 1, with a value of 0 indicating no correlation and values approaching -1 or 1 indicating a strong negative or positive correlation, respectively. Covariance also measures the relationship between two variables, but it is not standardized and therefore difficult to interpret. Inverse correlation is not a commonly used term in statistics. Multiple regression is a method of predicting a dependent variable based on multiple predictor variables. F-statistic is used in hypothesis testing for comparing the means of two populations.
