Document Summary
X and y are the variables measures. Xi is the ith score, where i can vary from 1 to n. Xi (the sum of the x variable from i=1 to n. The n above the can be a number, for example 3, and you therefore only calculate the sum of x1 through x3 and not all the way to xn. X2 = sum of the squared x scores. We are first to square the x scores, and then sum them ( x)2 = sum of the x scores, quantity squared. First we sum the x scores and then we square them. Numbers on the scale represent rank orderings, rather than raw score magnitudes. For example, in a spelling bee, the individual ranked as 1 is considered higher/better than the rest. Unites represent raw score magnitudes, there are equal intervals between adjacent units on the scale, and there is n absolute zero point.
