How to find regression line on ti 84.
The slope of a regression line is denoted by 'b,' which shows the variation in the dependent variable y brought out by changes in the independent variable x. The formula to determine the slope of the regression line for Y on X is as follows: b = (N∑XY- (∑X) (∑Y) / (N∑X2- (∑X)2) This has been a guide to what is Regression Line ...
23.1 Simple Linear Regression.
