Wait, can we really analyze string lengths without affecting the model size?

I recall that calculating averages isn't the same as analyzing frequency distribution, so option B seems off to me.

Hmm, I'm not sure which option is the best here. I'm torn between C and D. I think I'll try C first, since adding a column in Power Query seems like the most straightforward solution. If that doesn't work, I'll switch to option D.

I've got this! Option C is the way to go. Adding a column in the Power Query Editor is the best approach to get the string length information without impacting the model size. I feel confident about this one.

I'm a bit confused here. Should I be using a DAX calculated column or a Power Query function? I'm not sure which one would be better for this scenario. Maybe I'll start with option A and see if that works.

Okay, let's think this through. I'm leaning towards option D - changing the distribution for the Column profile to group by length for col1. That seems like the most efficient way to get the frequency distribution without adding any extra columns.

Hmm, this looks like a tricky one. I think I'll go with option C - adding a column in the Power Query Editor to calculate the length of col1. That way, I can analyze the frequency distribution without affecting the size of the model.

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!
