A protessor obtains SAT scores and freshman grade point averages (GPAS) for a group of n = 15 college students. The SAT scores have a mean of M = 580 with SS = 22,400, and the GPAS have a mean of 3.10 with SS = 1.26, and %3D SP = 84. Find the regression equation for predicting GPA from SAT scores. (Use five decimal places for the slope.) What percentage of the variance in GPAS is accounted for by the regression equation? (Compute the correlation, r, then find r2.) Percentage predicted = Percentage not predicted Does the regression equation account for a significant portion of the variance in GPA? Use a = .05 to evaluate the F-ratio.

Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.
