I have data that includes some variables which are nominal (like gender-Male, female,other) and few other ordinal data variables whose values are from 1 to 5 (1-Very bad…5-Outstanding). There are some continuous variables such as salary.
Included dummy variables for nominal data and scaled the continuous variables using scale() function in R.
Should I scale the ordinal data variables as well using the scale() method or should they be included as is.
I want to create a model using classification techniques with this data and my target is categorical variable.
