Document Summary
. a pearson correlation of r = +1. 00 between x and y indicates each time x increases, there is a perfectly predictable increase in y. A set of n = 5 pairs of x and y values has x = 10, y = 20, and xy = 10. a set of n = 5 pairs of x and y values has ssx = 10, ssy = 40 and sp = 10. For these data, the pearson correlation is _____. r = 10/20 = 0. 50. The pearson correlation is calculated for a sample of n = 25 individuals. As the sample size gets larger, the size of the correlation necessary for significance gets smaller. The pearson and the spearman correlations are both computed for the same set of data. The original data are measured on an ordinal scale of measurement. which of the following characteristics of the relationship between x and y is not measured by a.
