OLS regression is best applied when both the independent and dependent variables are measured at the interval level or higher. Nominal and ordinal variables do not have a clear linear relationship and may require different statistical methods. Ratio level variables have a clear interpretation of zero, while interval level variables do not, but both can be effectively analyzed with OLS regression.
