@m0sh1 Yes R2 score will not change much, but its important from interpretation stand point of view. The categories, even though they are represented by numbers are essentially categories. For example, 3 is for defenders, 4 is for goalkeepers, here 3 < 4 does not make sense since these are both categories. Also, since there are multiple predictors, the impact of one hot encoding will not necessarily have a lot of impact on the R2 score, but will have correct interpretations for each category. Yes, the impact of big_club is significant on the predictions and it makes sense from interpretation point, if a player is from one of the Top 6 clubs, they will most likely have higher market value. But remember, for simplicity, we haven’t used any Standardization methodologies for this homework and Standardization might have some impact on the coefficients.
