typo in section Removing Duplicates

[codeandstats]

Regarding section

I believe the False in the following sentence should be a True ?

Relatedly, drop_duplicates returns a DataFrame with rows where the duplicated array is False filtered out

Thanks for the report — I think the issue is the interpretation of "filtered out". For some this might mean "included" and for others "excluded". I will update the text to be clear that it means "excluded".
