Hi. I'm reporting some stats on my website, and I want to adjust my stats by the demographics. Been a long time since HS math... and I never studied stats anyway. The following reads more complicated than it really is. Of the 4095 users that filled out my questionnaire, 3255(79.5%) are female, 772(19%) are male and 68(1.5%) did not specify. My users lump themselves into 1 of 14 categories (the categories are unimportant). We need look at only one category for now. 91 users that specified a gender were lumped into category #1. Of those 91 users, 70 were female and 21 were male. or 77% females and 23% males. That's more males than average. And that is the interesting piece of information I want to capture here: that Category 1 is a male-dominated category, despite the sheer number of female users that are in it. (I'll do the same for the other 13 categories.) What I'm not sure about is how I demonstrate this difference in a graph with numbers. What numbers do I end up with after I've compensated for the gender bias in the above example? I think I should end up with numbers like this - males: 54%, females:46% or thereabouts. i'm not sure how to get here from there.
