>>12498077>>12498047It's actually stupider, because instead of a category (organic banana, regular banana), column A was also a number, and they sorted that alone as well. So ignore my previous example a bit:

So, to formulate a different problem: Let's figure out if rich people have a bigger grocery story bill.

In column A, put a persons income, and column B, their grocery bill. So A1 will be the income of person A, and B1 will be their bill.

Cool! Data. Now, add a trendline: y=mx+b. This is a regression line, and plots the association between income and grocery spending. Awesome! But wait, lets pretend we are retarded, and I don't like that its not a straight line. How do we get straight line?

Now sort column A by itself, smallest to largest. Then column B by itself, smallest to largest. If you're thinking "what the fuck" you are on the right track.

Now, plot the independently sorted X to the independently sorted Y.

Wow! A line! Now that's a relationship!

Mull it over. Don't overthink it; its as stupid as you think it is.
