Linear regression with a categorical covariate
I'm new to JASP. For a course I'm teaching, I want students to run a simple linear regression on a continuous dependent variable, in which one of the covariates is categorical - say an eight-category variable capturing respondents' ethnicity.
I can't seem to figure out how to get regression estimates for each category in relation to the reference category, as one would, say in Stata using an i.varname to indicate the variable i categorical. It makes no sense to get an overall estimate for ethnicity, as if it was continuous.
Any help on how to do this in JASP?
Thanks in advance.
