Questions:

1. This study examined a convenience sample. What does this mean?
2. Group one completes the pretest and posttest knowledge test before and after the simulation experience. The score is measured on a scale of 0-8. What level of measurement is this variable?
3. One of the student groups had their knowledge and performance measures assessed before and after the simulation, then again after repeating the simulation experience a second time. Multiple t-tests are utilized to examine the data from two different points in time. Would an independent t-test or dependent t-test be appropriate to compare the knowledge score on the pretest versus the test after the first simulation?
