B. The second alternative is not a factor that differentiates between within subjects and between subjects design. If done properly, both are equally efficient at determining cause and effect relationships.
Which of the following is not a factor that differentiates within-subjects and between-subjects designs? a. Within-subjects...
Between-subjects designs are subject to threats from whereas within-subjects designs are subject to threats from a. environmental variables; individual differences. b. individual differences; order effects c. order effects; individual differences. d. history effects; order effects.
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...
An advantage of a within-subjects design as compared to a between-subjects design is... a. All of these options. b. it eliminates the threat that participant characteristics may become a confounding variable. c. it reduces the variability by subtracting out the individual differences. d. it usually requires fewer participants.
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....
Time-related factors and other order effects can threaten internal validity for some within-subjects experiments. Describe the kind of study for which these factors can be a problem and explain how they can be a confounding variable in some within-subjects designs.
Which of the following is an advantage of within-groups designs? A. These designs avoid order effects. B. These designs avoid demand characteristics. C. These designs are always possible. D. These designs rely on fewer participants. Preregistration occurs at which point in the scientific process? A. Before data collection B. Before developing hypotheses C. After publication D. After replication According to the textbook, what is the problem with WEIRD samples? A. They are not very representative of the world’s population. B....
While within-subjects designs often require fewer subjects, that in itself can lead to issues in terms of the data. For instance, subjects are being used in multiple trials, so they would typically be more tired of the study, especially if it's the same general experiment performed repeatedly over consecutive trials. This can lead to multiple confounds, such as the subject not participating as they normally would, or even dropping out of the study and therefore nullifying any of the data...
Why is random assignment used in between-subjects experimental designs? a. To increase the variance within the groups. b. To eliminate systematic differences between the groups. c. To manipulate the independent variable. d. To avoid volunteerism.
State whether each of the following is an example of a between-subjects, mixed, or within-subjects two-way ANOVA design. (a) A psychologist administers a small, medium, or large dose of a drug to a sample of mice (Factor A: drug dose) and measures reward-seeking behavior across three experimental trials (Factor B: trials). between-subjects design or mixed design or within-subjects design (b) An industrial organizational psychologist measures the GPA among men and women graduate students (Factor A: gender) with low, medium, or...
1. The pretest-posttest nonequivalent control group design is also very commonly used in psychology. Which of the following is NOT a benefit of using this design when random assignment is not possible: It reduces the threat of assignment bias It limits threats from time-related factors It provides some evidence of a potential cause-effect relationship It rules out differential history effects 2. Particularly when they do not include a control group, pre-post designs are most vulnerable to ____________-related threats to internal...
