For a research study comparing two treatment conditions, a repeated-measures design would require one score for each participant but an independent-measures design would require two scores for each participant.
True or False
Solution:-
option A. True.
Explanation:
For a research study comparing two treatment conditions, a repeated-measures design would require one score for each participant but an independent-measures design would require two scores for each participant.
Between-subjects (or between-groups) study design: different people test each condition, so that each person is only exposed to a single user interface. Within-subjects (or repeated-measures) study design

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
One concern for a repeated-measures study is that a participant’s score in one treatment may be influenced by practice or experience gained in a previous treatment True or false?
contrasting a repeated measures research design with matched subjects and independent measures designs A graduate student is interested in whether journaling can affect grief and healing. She has participants who have been widowed within the past 10-14 months complete a battery of psychological questionnaires before and after journaling about their daily problems for 2 months. The first time the graduate student conducted this study, she used a repeated-measures design and compared the widows' and widowers' baseline scores with their scores...
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...
answer all please In an analysis of variance, the MS between and MS within represent the means of the squared variability between and within conditions. True • False QUESTION 14 If an analysis of variance produces SS between 30 and MS between 10, then the ANOVA is comparing three treatment conditions. True False QUESTION 15 Compared to an independent measures design a repeated measures study is more likely to find a statistically significant effect because it reduces the contribution of...
7. An advantage of the matched groups research design is that it: provides a less ambiguous interpretation of the results than the repeated measures design. has more statistical power than the between-groups design with random assignment. requires fewer research subjects than the repeated measures design. has more statistical power than the repeated measures design. 8. One way to increase the statistical power within a between-groups design is to: have each participant contribute two data points per condition. match participants on...
The following data represent the results from an independent-measures study comparing two treatment conditions. Treatment One Treatment Two 7.4 5.4 5.4 2.4 7.5 4.7 6.3 5.9 6.6 5.3 8.7 3.7 6.8 2.3 Run the single-factor ANOVA for this data: F-ratio: p-value: Now, run the t test on the same data: t-statistic: p-value: Consider how these are the same or different.
An independent-measures study comparing two treatment conditions produces a t statistic with df = 18. If the two samples are the same size, how many participants were in each of the samples? a) 9 b) 10 c) 19 d) 20
In a repeated-measures study the sample mean and variance are computed using the difference scores for each participant. True or False
19. A repeated-measures study comparing two treatments with a sample of n 10 participants produces a mean of M 8 for the scores in the first treatment, a mean of M 10 for the scores in the second treatment, and a mean of MD 2 with Sum of squares of the difference SS 64 for the difference scores. What is the estimated standard error for the sample mean difference? Answer:
