I think the OP understands this. I'm not sure you understand what the OP is asking for. It has nothing to do with "accepting the answer" the punnett square gives. The OP wants actual numbers of actual clutch results, like Freakie Frog gave.
Tattlife, I know I don't understand WHY you are asking, other than you said a paper for school. I don't see how it will be a very interesting paper. Either you'll get enough responses that it will be very close to the expected 50% ratio regardless of whether mom or dad was the spider, which for sure won't make an interesting paper. Or you will get an answer that appears to differ, in which case the only intelligent thing to say about it is that you must not have had a big enough sample to get statistically relevant information.
Also, have you considered that while it will be relatively easy to find small breeders like Freakie who can give you actual clutch results for male spiders, there are far fewer people who have had clutches from female spiders. That will have a big effect on your paper also.
You might consider a different subject?
