We are testing the hypothesis that frequent users of Facebook will have a significantly different level of self-esteem than infrequent users of Facebook. We calculated a T-Test for these two groups: Frequent users of Facebook- separate mean Infrequent users of Facebook. Solution the formula for F ratio= variance of 1st sample/variance of 2nd sample. (1) Male- Frequent/Infrequent-separate means = 50/18= 2.778 (2) Female- Frequent/Infrequent- separate means =165.33/67= 2.468.
