If the data is too long, you can always just shorten the column. Problem solved!

I heard Power BI can also calculate the length of your hair. Gotta keep that model lean and mean!

That's interesting! Power BI can do a lot of things, but I don't think it can calculate hair length.

Option D? Seriously? Grouping by length? That's like trying to catch a fish with your bare hands. Power Query is the obvious choice here.

Hmm, I was thinking of using a DAX calculated column, but you're right, that might increase the model size. Power Query is definitely the way to go!
