Psychological Methods, 13, 203229. One way to guarantee this is for the Since you want to determine whether strong agreement is associated with a particular nominal outcome class, you could run polytomous logistic regression with nominal class as the dependent variable and 4 binarized (0,1) dummy variables as predictors, representing the 4 ordinal levels (5-1) with level 1 as the corner point. A hit is when they select the right fruit, miss is when they select the wrong type of fruit. Hoffman, L. (2019). This is really the only sense in which it makes sense to talk about 'correlation' for a categorical random variable. Structural Equation Modeling, 30(2), 296314.

Expanding the Bayesian structural equation, multilevel and mixture models to logit, negative-binomial, and nominal variables. In Frontiers in Education, 5, 589965. Correlation is a measure of the relationship between two variables, and it can be either positive (meaning that the two variables tend to increase or decrease together) or negative (meaning that they tend to move in opposite directions). The following information was provided about Phik: Phik (k) is a new and practical correlation coefficient that works consistently between categorical, ordinal and interval variables, captures non-linear dependency and reverts to the Pearson correlation . 1: Not at all satisfied; 10: Completely satisfied. of measurement. For any outcome $C=k$ we can define the corresponding indicator $I_k \equiv \mathbb{I}(C=k)$ and we have: $$\mathbb{Corr}(I_k,X) = \sqrt{\frac{\phi_k}{1-\phi_k}} \cdot \frac{\mathbb{E}(X|C=k) - \mathbb{E}(X)}{\mathbb{S}(X)} .$$.

Bolger, N., Davis, A., & Rafaeli, E. (2003). Either of the extremes (-1 & 1) represent very strong relationship and 0 represents no relationship. Nominal variables have no inherent order, while ordinal variables have a natural order. Mplus does provide a column with a one-tailed p value in its default output. It should be noted, though, that the point-polyserial correlation is just a generalization of the point-biserial. Asking for help, clarification, or responding to other answers. 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. Examples of ordinal variables include overall status (poor to excellent), agreement (strongly disagree to strongly agree), and rank (such as sporting teams). Journal of Happiness Studies, 4(1), 3552.

Correlation between Categorical Variables | by Ritesh Jain - Medium It is a basic idea of measurement theory that such a variable is invariant to relabelling of the categories, so it does not make sense to use the numerical labelling of the categories in any measure of the relationship between another variable (e.g., 'correlation'). If you want to take a different approach, you could get complex and look at a multilevel model, with subject being repeated. Where does the version of Hamapil that is different from the Gemara come from? For the size of the association, there are a few different effect size statistics, like Cliff's delta (rank biserial correlation) or Vargha and Delaney's A for two categories; or maximum CDA or VD, or epsilon squared or Freeman's theta for more categories.
