The number of degrees of freedomassociated with the t test, when the dataare gathered from a matched pairs experiment with 13 pairs, is
For a set of data, the total variation or sum of squares for y is SST =180, and the error sum of squares SSE =54. What proportion of the variation in y is explained by the regression equation?
The degrees of freedom = 13 – 1 = 12
The proportion of variance in y …
The proportion of variation in y for a regression analysis is determine. The degree of freedom is determined.
