Holding all else equal (e.g., sample size, effect size), will an independent-samples t test or a repeated-measures t test result in more statistical power?
A) Independent Samples T-Test
B) Repeated Measures T-Test
Correct option is B:
B) Repeated Measures T-Test
(since it reduce between subject variance a same or paired subject are used)
Holding all else equal (e.g., sample size, effect size), will an independent-samples t test or a...
What would be the minimum sample size for an independent samples t-test with a small effect size where eta squared = .01, alpha = .05, and statistical power = .70?
For each example, state whether the one-sample, the two-independent-sample, or the related samples t-test is most appropriate. If it is a related samples t-test, indicate whether the test is a repeated measures design or a matched-pairs design. 1) A researcher matches right-handed and left-handed siblings to test whether right-handed siblings express greater emotional intelligence than left-handed siblings. A. one-sample t-test B. two-independent sample t-test C. related samples t-test using the repeated measures design D. related samples t-test using the matched-pairs...
Make your own research question for each A) z-test B) t-test C) independent samples D) related samples ANOVA A) one-factor, independent measures B) one-factor, repeated measure ex. "My study": Does deafness effect quality of life for individuals living in underdeveloped countries.
Problem Set 7.1: t Test with Related Samples Criterion: Differentiate between independent samples, repeated measures, and matched samples. Data: Scenario A: A researcher wants to know whether men or women spend more money at the movie concession stand. He asks the concession clerk to identify customers as male or female by marking their gender on each saved receipt. Scenario B: A CPR instructor wants to know if her students are learning anything during her 90-minute training. She decides to quiz...

6. Engagement Activity: The t Test for Two Related Samples In the last chapter, you were introduced to Professor Ken Bonanno's Statistical Methods in Psychology class, where students are asked to complete a research study as a part of the semester-long course. Many of his students' research questions could be asked using the independent-measures t test, but there are other approaches, which will be explored in this chapter. Click the following topics to see some sample questions asked by Professor Bonanno's students....
What is an advantage of using a related-samples t-test over an independent-samples t-test? There is a carry-over effect with the related-samples t-test .None of the options. The related-samples t-test needs less participants. There is a maturation effect in the related-samples t-test.
How is the Dependent Samples t Test different from Independent samples t Test in terms of samples? What are similarities in the assumptions behind both the Dependent and Independent Samples t Test? What is Dependent Samples t Test with one sample also known as In a dependent Samples t test what is the df for a sample of 100 participants in a particular study?
