A researcher conducts an experiment comparing two treatment conditions with 20 scores in each treatment condition. a. If an independent-measures design is used, how many subjects are needed for the experiment? Explain how many samples will be needed, how many subjects, and what is the total subjects b. If the researcher used a repeated-measures design, how many subjects participated in the experiment? would the repeated –measures design use the same sample of n-10 and will there be 10 subjects in both treatment conditions.
c. If the researcher used a matched-subjects design, how many subjects participated in the experiment?
we are discussing matched-subjects design would it require two separate samples with n=20?
