A researcher used a two-group quasi-experimental (nonequivalent control group) design to test the effect of a Tai Chi intervention on quality of life in nursing home residents. The elders’ age was statistically controlled. What procedure for statistical control might the researcher have used? A. Propensity score matching B. Analysis of covariance C. Manipulation checks D. Power analysis

Think of observation then form a question and hypothesis. Then,
design an experiment you could do to test your hypothesis. Make
sure the experimental design is detailed and define all of your
variables (the dependent variable, the independent variable, the
controlled variable, designing the procedure, level of treatment,
replication, the control. )

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...

Which of the following are valid reasons for doing a factorial experimental design? (select the 3 correct answers) A. It's easier to establish control and eliminate confounds B. You can test multiple variables simultaneously C. The complexity of the situation would be more like what's found in the real world D. It allows you to see interactions between variables

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....

For this Discussion, think of a specific testing scenario. Then consider a reliable test item for that testing scenario and an unreliable item for that same testing scenario. Consider how you might know if these items are reliable or unreliable. With these thoughts in mind: Post a brief description of a specific testing scenario. Then describe one reliable test item and one unreliable test item for that testing scenario. Finally, explain what determines whether an item is reliable or unreliable...
