Frontiers in Psychiatry, 11, 214. Choosing a nonparametric test & Savord, A. This viewpoint regarding categorical outcomes is not unwarranted for technical audiences, but there are non-trivial nuances in model building and interpretation with categorical outcomes that are not necessarily straightforward for empirical researchers. An ordinal variable is similar to a categorical variable. (doi:10.1177/8756479308317006), you should consider kendall's tau-b if the number of items in your ordinal variable is low (<5 or <6 this is a bit arbitrary). Roughly speaking, Kendall's tau distinguishes itself from Spearman's rho by stronger penalization of non-sequential (in context of the ranked variables) dislocations. it doesn't mean anything to calculate the correlation between two variables if they are not quantitative. but we would say that it is an ordinal variable.

So for each subject I indeed have 6 preference ratings, and 6 accuracy ratings. between the values of the numerical variable are equally spaced. However, covariates can also be lagged effects if the hypothesized effect is thought to take more time to unfold (e.g., binge eating avoidance yesterday predicts Adherence today) or to delineate between the cause and effect more clearly if one variable was not necessarily collected first within time t. In such case, autoregression in the covariate may be added to the model. Accessed 31 Mar 2023. Thank you a lot. For a general categorical variable $C$ with range $1, , m$ you would then just extend this idea to have a vector of correlation values for each outcome of the categorical variable.
