Linear Regressions Vocab

The _______________ is a method that creates a regression line for a scatter plot that has two basic requirements:

1) the line must contain the centroid of the data set, and

2) the sum of the squares of the vertical distances from each given data point is at a minimum with the line.

The _______ is a point whose x-value is the mean of all the x-values of the points on the scatter plot and its y-value is the mean of all the y-values of the points on the scatter plot.

On a scatter plot, a __________ is a mathematical model that can be used to predict the values of a dependent variable based upon the values of an independent variable.
