Can you run correlation with ordinal data?
Pearson correlation is not suitable for ordinal data. Usually Liker scale represents Agree – Disagree responses. The Pearson’s correlation coefficient measures linear correlation between two continuous variables. Values obtained using an ordinal scale are NOT continuous but their corresponding ranks are.
Can a continuous variable be ordinal?

How is an ordinal variable different from a continuous variable?
An ordinal variable: subjects are asked to rate their preference for 6 types of fruit on a 1-5 scale (ranging from very disgusting to very tasty) On average subjects use only 3 points of the scale. A continuous variable: the same subjects are asked to quickly identify these fruits, which results in an mean accuracy for the 6 fruits.
What is the difference between categorical, ordinal and…?
A purely categorical variable is one that simply allows you to assign categories but you cannot clearly order the variables. If the variable has a clear ordering, then that variable would be an ordinal variable, as described below.
How to calculate the correlation between an ordinal variable?
I’d like to estimate the correlation between: An ordinal variable: subjects are asked to rate their preference for 6 types of fruit on a 1-5 scale (ranging from very disgusting to very tasty) On average subjects use only 3 points of the scale.
Which is an example of a continuous variable?
Some good examples of continuous variables include age, weight, height, test scores, survey scores, yearly salary, etc. Kendall’s Tau is often used for correlation on continuous data if there are outliers in the data. Ordinal variables are categories that have an inherent order.
