Document Summary
Giving 95% wiggle, margin of error and make a con dence interval around the score. Zero being inside or outside the interval, if its outside could dismiss the possibility that it could be zero: if zero is the upper or lower bound p = 0. 05, and is stat sig. Calculating t ratio, same as simple experiment and analysis of variance: uctuation of diff points to another. Is an extension of simple regression to use two+ independent variables: more than 2 would need a software for the calculations. Y" = a + bx: y" is predicted cals in donut based on variable x. Y" = a + b1x1 + b2x2 + . Slopes indicate the individual effect of an independent variable controlling for effects of the other independent variable. Slope indicates the unique effect of an independent variable, above and beyond the effect of other independent variables.
