In the Question 5 we have to compare models and one is considered better if:
at least 7 of the cross-validations scores are better
That is the case if better means better or equal
(what I thought but got the answer wrong because in the explanation, it means stricly better
:
5-NN with StandardScaler is strictly better than 5-NN with MinMaxScaler for ...
That is very confusing because a lot of tests scores are equals. The question needs to be clearer
