Do you seriously understand "First you'd have to prove that they aren't. Just saying the numbers are not the same doesn't mean much." as "you would not simply accept numbers that were different"?
A number itself just does not mean much. Here, have an example:
- 90% of all people in Yoga-Clubs are women (<- random number, I don't know if it's really 90%)
Your reaction:
"OH MY GOD, YOGA-CLUBS DISCRIMINATE AGAINST MEN!!!!!!!!!!!"
My reaction:
"Okay, let's take a look that these numbers mean. Let's ask 20000 men and 20000 women what they think about Yoga. Aha, aha. 97% of these men say they have no interest in Yoga. 50% of the women say they have no interest in Yoga. Well, that probably explains some of the gap. Let's check for other factors (etc.)"
If you really think your reaction (just seeing a raw number and thinking you can draw a conclusion from that) is correct and my reaction (seeing a raw number and wanting to break it down into all things that influence the raw number) is just trying to do some nefarious stuff, then I feel sorry for you, because you have no idea how wrong you are.
