SOC222H5 Lecture Notes - Covariance, Location Test, Coefficient Of Determination
Document Summary
Soc222 measuring the social world: session #4 correlation & Terms to know effect size, linear (equation), parameter, constant a , slope b , variance, covariance, definition formula, computational formula, correlation coefficient r , scatter, outlier, proportion of variation explained (pve), coefficient of determination r2, eta greek letter. Some of the terms we have looked at before. This is what happens when you have 2 ratio variables. Rq: are your marks higher if you spend more time on campus? is there a relationship between the 2 variables and if there is, what is the effect size. how big/strong is the relationship. Ranges from 0-6, most are there almost every day while 3 are never on campus. The relationship is slightly positive: the first step: Find the regression line that fits the data best. Best fit means: it comes the closest to all the points (cases)
