Match the statistics term with its BEST definition. Question 2 options: A key requirement for using correlation and regression models is to collect this type of data. With bivariate data, the result of MINIMIZING the sum of squared distances between the observed and predicted values (residuals) for a linear model. This quantity is computed by subtracting the observed response variable from the predicted response variable. With bivariate data, when one variable increases a second variable decrease implies this relationship. A...
