I really suck at this so hope you could help me
ve a group of people attending a training course, in order to measure whether the training course is effective in improving attendees' knowledge. We did the following:
attendees will complete a pre-test (TRUE or FALSE only) before the training attendees attending the training attendees will complete a post-test (TRUE or FALSE only) after training
Both pre and post tests are having exactly the same questions, However the test is NOT tagged with barcode so i have NO way to know if a certain pre and post questionnaire belong to the same individual
Each paper has been scored out of 20 ,, and the scores i have entered in SPSS for every student for both the pre and post questionnaire
So for this can i just use the paired t test and will the interpretation still be valid or is there an alternative i can use to find the significance of the intervention and whether it was effective or not? or should i do the t-test to the sum of the scores for pre and post?
