Document Summary
A statistic that represents the extent to which the same individual or event occupies the same relative position on two variables; The pearson r statistic ranges from -1. 00 to 1. 00. In a perfect negative correlation, r = -1. 00. In a perfectly positive correlation , r = +1. 00. There is no apparent relationship, r = 0. 00. R provides some indication of the degree of relationship between the two variables. To calculate this level of reliability (statistical significance: determine df: df = npairs 2 (df compensates for small n by requiring a large absolute r, formulate hypothesis (h0= no relationship, h1 = true reliable relationship) Value of sig tells you how probable is it that the value you got is due to chance. One useful function of correlational analysis is that they can be used to predict the outcome of a variable.
