Document Summary
Who to use as participants and how many. Exact procedure: level of description when writing up study. Manipulation checks: checks to ensure that the manipulation of the iv actually worked the way you wanted it to. Usually, it"s harder to get participants and this isn"t a problem. In general, minimum # that you"re supposed to have in each group = 30 nobody knows where this # came from. Ex) 3x2 design = 6 cells = 30x6 = 180 participants needed. So consider how many variables and how many levels you want be practical because then you"ll need a lot of participants. Best case = randomly select sample from population of interest but most of the time, not done most of the time = convenience samples with undergrad @ uni: convenience, snowball. You ask your friend to ask some of their friends and so on forward by email.
