c. correction, nominal

d. correlation, interval

Answer 1

The correlation is measures of the linear relationship between two variables.

A nominal variable sometimes called as categorical variable.

For example, gender is a categorical variable having two categories one is male and other is female.

So we use the nominal variable in Pearsons r measures.

The correct option is:

b. correlation, nominal
