I need to find the mean calculating calculate a T-test on the two groups:

(1) Frequent users of Facebook- separate mean

(2) Infrequent users of Facebook. separate mean

b) Part IV F-Ratio

i) Use the data you compiled from the surveys to calculate an F- ratio on the 4 groups (4 means to calculate):

(1) Male- Frequent/Infrequent-separate means

(2) Female- Frequent/Infrequent- separate means

If your group consists of members of the same sex, then use ages to separate the groups: For instance, under-30, over-30, etc.

Sarah = 3, 4, 3, 4, 2, 2, 3, 3, 3, 1 (frequent user) age 28

Emily = 5, 5, 4, 5, 2, 2, 5, 2, 3, 1 (frequent user) age 38

Sue = 3, 1, 3, 3, 1, 1, 1, 3, 1, 3 (infrequent user) age 40

Mary = 3, 2, 3, 3, 4, 2, 4, 3, 2, 3 (frequent user) age 48
