WebUse Pearson's r and Spearman's rho to assess the association between two variables that have ordinal categories. Ordinal categories have a natural order, such as small, medium, and large. The coefficient can range in value from -1 to +1. The larger the absolute value of the coefficient, the stronger the relationship between the variables. WebFeb 4, 2024 · The Pearson χ 2 test statistic for differences in a contingency table between a set of observed counts ( O i) and those expected based on a null hypotheses like independence, E i, is: χ 2 = ∑ i = 1 n ( O i − E i) 2 E i where the sum is over all cells i of the contingency table.

WebTypically a Reduced Chi-square value close to 1 indicates a good fit result, and it implies that the difference between observed data and fitted data is consistent with the error variance. If the error variance is over-estimated, the Reduced Chi-square value will be much less than 1.
