I ran an OLS model on a dataset with 2 categorical variables. One of them was gender. The other one had 3 different categories. I used one-hot encoding for it during pre-processing before running my model.
Variables in the image: Embarked_C and Embarked_Q. The results showed a p-value for Embarked_Q as 0.785. In this case, should I remove both Embarked_Q and C or just Q?
