# Thread: help! t tests and alpha sets at .05

1. ## help! t tests and alpha sets at .05

I am trying to produce a sample theoretical experiment on paper. I've come up with my problem, hypothesis, subjects, apparatus and procedure.

I do not quite understand how to produce the statistics. I know I'm suppose to use a 't test' but what is suppose to go in the statistic and how do I find that out. Also apparently the "result" is what came out of the test and whether the hypothesis was rejected or not.

Please assist as I do not understand the whole alpha .05 and 't tests'.

My experiment was to test 3 years old at a day care to see if watching an animated action clip from spiderman would have an effect on behavior. the group was split into two. one who remained with normal activities and the other group who watched the 20 min clip. the whole group was observed before the clip, then the group watching the cartoon was observed during the clip and then everyone was observed after the clip together. I am using a scale from 1-5 to document the observations; 1 being friendliest to 5 as the most agressive behavior. Please help. Am I doing the study wrong - what is the best way to come up with numbers for this.

I need to get the 'statistic' and 'result'
