i am working on my year-end stats project, which was an observational experiment
my hypothesis is that men are more likely to ask for help if they are by themselves than if they are with their wives or girlfriends
the method, in short, was that while i was at work, i noted the gender and grouping of people who asked for help from employees. the groups are "alone", "couples", and "2+ of the same gender / mixed group"
i have 273 pieces of data
141 m 132 f
126 alone 91 couples 56 groups
the problem is this: what test statistic(s) should I run (I'm using SPSS) to determine whether or not my hypothesis was accurate (and so on)?
i have perused my notes, but we never really did any problems quite similar enough to this to be of use.
Hey I'm no statistician but to accurately determine if men are more likely to ask for help when they're not with their wives/girlfriends, shouldn't you also have recorded how many men DIDN'T ask for help? Who's to say men aren't more likely to come into the store alone?
P = proportion that asked for help, Q = proportion that didn't ask for help Pop 1 = population without SO, pop 2 = population with SO Mean = P1-P2 SE = something like sqrt(P1Q1/n1 + P2Q2/n2)
If the margin of error doesn't include 0, you reject the null hypothesis.
I have doubts about the design of the experiment, but that's the math for you

i sort of gave you guys the shorthand.
i have more stuff that clarifies these things - it's costco, so everyone who comes in is a member, i got membership demographics from one of the managers, and it's like 52% M, 48% F
What you're testing is whether a man is more likely to be with his SO if he asked for help. To know if a man is more likely to ask for help if he's with his SO, you'd need to know how many couples enter and how many single men enter.
You're still testing something, but it's different from what you think it is.
