I've conducted a survey for my thesis where I ask a series of questions of the format:
A statement relating to the experiment
Then the participants answer strongly disagree (1) --> strongly agree (5)
I have 14 responses and two groups, one control and one experimental (7) in each. With the answers to each of these questions, I have checked for statistical significance in each question by use of a Z-test, however I was reading this morning that my data may be ordinal and small sample size, in which case I should use a T-test.
Is my initial approach valid still?
