## How do you correlate nominal and ordinal?

So there is no correlation with ordinal variables or nominal variables because correlation is a measure of association between scale variables. However, the optimal scaling procedure creates a scale for nominal variables (and ordinal), based on the variable levels’ association with a dependent variable.

**What is the variable for correlation?**

The linear correlation coefficient is a number calculated from given data that measures the strength of the linear relationship between two variables: x and y. The sign of the linear correlation coefficient indicates the direction of the linear relationship between x and y.

### How do you correlate nominal and scale data?

To do correlation between nominal variable and a scale, make sure the nominal is variable is dichotomy, then you can do point biserial correlation. When the nominal variable is more than 2 categories, correlation test violate the assumption of linearity.

**Can you correlate nominal data?**

Nominal data currently lack a correlation coefficient, such as has already defined for real data. A measure is possible using the determinant, with the useful interpretation that the determinant gives the ratio between volumes.

## How do you find the correlation between ordinal variables?

According to the (Research Methods for Business Students) book, to assess the relationship between two ordinal variables is by using Spearman’s rank correlation coefficient (Spearman’s rho) or Kendall’s rank-order correlation coefficient (Kendall’s tau).

**Can you run correlation on nominal data?**

### Can Pearson correlation be used for nominal data?

Since your measurement scales are nominal and ordinal you could not apply the parametric test like Pearson product Moment Correlation.

**Can you use Spearman correlation on ordinal data?**

The Spearman rank-order correlation coefficient (Spearman’s correlation, for short) is a nonparametric measure of the strength and direction of association that exists between two variables measured on at least an ordinal scale.

## Which correlation coefficient is used for ordinal with rank?

Spearman’s rank correlation coefficient

Spearman’s rank correlation coefficient, 𝑟𝑠 shows the correlation between two ordinal data.
