1,4. Since a between subjects design uses different participants for each treatment condition, each participant will have a single score. However, a within subjects design uses the same participants for all treatment conditions as a result of which, each participant will have four scores.
Dr. Can-Adian will be conducting an experiment comparing 4 treatment conditions. If she uses a between-subjects...

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
6. Typically, when comparing a within-subjects design to a between-groups design which of the following describe their differences in error variance? a. Within-subjects designs results in less error variance than between-groups. b. A within-subjects design results in more error variance than a between-groups design. C. A within-subjects design results in the same amount of error variance as a between-groups design d. There is no error variance in a within-subjects design, whereas a between- groups design does present some error variance....
Dr. Strange is attempting to counterbalance his within-subjects research design that has 3 conditions, but he isn't sure whether to use complete or partial counterbalancing. If Dr. Strange uses complete counterbalancing he would have groups, whereas if he uses partial counterbalancing he would have groups. In this example, groups = number of orders of treatment conditions. a. 6;3 b. 3; 6 c. 9,5 d. Cannot answer without more information
QUESTION 17 A researcher conducts an experiment comparing four treatment conditions with a separate sample of n-6 in each treatment. An ANOVA is used to evaluate the data, and the results of the ANOVA are presented in the following table. Complete all missing values in the table. Hint: Begin with the values in the df column.

Dr. Pena is conducting research to see whether the severity of the chronic headaches suffered by her patients will be lessened through the use of biofeedback. Based on what she has read in medical journals and on her own observations, Dr. Pena has determined that the headaches are caused by muscle tension, so she feels that patients who learn to relax will have fewer or less severe headaches. To test her theory she attaches electrodes to the forehead of each...
