Dr. Can-Adian will be conducting an experiment comparing 4 treatment conditions. If she uses a between-subjects design participants will have score(s) each, but if she uses a within-subjects design participants will have score(s) each. a. 1; 1 b. 4; 1 c. 1: 4 d. 4; 4
A researcher conducts an experiment comparing two treatment conditions and obtains 20 scores in each treatment? Which design would require the smallest number of subjects? a repeated-measures design an independent-measures design a matched-subjects design either an independent-measures or a matched-subjects design
3. Repeated-measures and matched-subjects experiments Aa Aa Repeated-measures experiments measure the same set of research participants two or more times, while matched-subjects experiments study participants who are matched on one or more characteristics. Which of the following are true for both a repeated-measures experiment and a matched-subjects experiment when used to compare two treatment conditions? Check all that apply. The researcher computes difference scores to compute a t statistic. □ If the researcher has n number of participants to use...

A researcher conducts an experiment comparing three treatment conditions. The data consist of n = 34 scores for each treatment condition. a. If the researcher used an independent-measures design, then how many individuals were needed for the study and what are the df-values for the F-ratio? Explain in detail and be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers. b. If the researcher used...
