The group assignment for your research subject is to critique an assigned quantitative study. To proceed, you must first decide on the design to be used: you think it is a before and after design; the others in the group think it is an experimental design because it has several explicit hypotheses. How would you convince them that you are correct?
What will be an ideal response?
ANSWERS It would be advisable to ensure that the project's aim was to measure the effect of an intervention, before and after its introduction. It should be noted that before–after designs can still have hypotheses, but they lack one or more of the controls required in an experimental design. That is, there may be no control of contamination between groups, or there is no randomisation of allocation to treatment and control groups.
