Finding mean, median, standard deviation and standard error for each group

A researcher is interested in whether social assertiveness might be influenced by training procedures. Two groups of college sophomores are randomly selected. Group A subjects are assigned to the "training sessions" and Group B subjects do not receive the training. Both groups are given a "Social Assertiveness" test (higher scores indicate greater assertiveness). The results are the following:

Group A: 14, 11, 10, 10, 8, 6, 5, 9, 7, 9, 10, 9, 7, 8, 9, 10, 11

Group B: 12, 10, 10, 8, 7, 6, 4, 2, 5, 4, 6, 3, 8, 6, 5, 4

Work out the mean, standard deviation, median, and standard error for each group.
