Which type of statistical test would be appropriate for this design?
What source of variation is found in an ANOVA summary table for a within subjects design that is not in an ANOVA summary table for a between subjects design. What happens to this source of variation in a between-subjects design?
Below are several research scenarios. Indicate which set of statistical analyses (e.g., ANOVA, independent samples t test, correlated samples t test, correlation, chi-square, regression) should be used to analyze the data collected in study, and explain why that statistical test should be used. (a) Teachers at a local middle school were interested in exploring the effects of a collaborative peer tutor teaching program on the motivation levels seventh-grade students. Four of eight classes of seventh grade students were randomly selected at Bulloch Middle School to serve as subjects in this study. Students within each class were then randomly assigned to one of three groups: a collaborative peer tutor teaching program, group learning activities, or individual learning activities. Each class was taught by a different teacher. The Middleman motivation scale was used to measure motivation in the subjects, and this scale produces scores that range from 1 to 25 with higher scores indicating…
A group of cognitive psychologists were interested in testing whether learning in the testing environment improves memory retention (i.e, test scores) in a scuba diving class. To test this, the experimenters manipulated learning location such that half learned the material in a pool. in addition, the experimenters manipulated testing location such that half. of the class were tested in the classroom and half were tested in the pool. thus, a 2X2 design was used. Which statistical test should be used? a. one way between subjects ANOVA b. one way repeated measures ANOVA c two way between subjects ANOVA d. none of these options
. A researcher is using a one-way ANOVA to see whether a significant difference can be found between 3 types of teaching methods in students’ success. How would you phrase the null hypothesis? How would you phrase the alternative hypothesis?
What is H0 for a one-way ANOVA? If H0 is rejected, does that imply that each mean is significantly different from every other mean? What information do you need to decide on a sample size that will provide adequate statistical power? If there is an overall significant F in a one-way ANOVA, can we conclude that the group membership or treatment variable caused the observed differences in the group means? Why or why not?
describe the difference between a one-sample t-test, a two-sample (independent-samples) t-test, a repeated measures (related-samples) t-test, and the analysis of variance (ANOVA).
If the null hypothesis is rejected for a One-Way ANOVA, then what test should you conduct?
As part of a long-term study of individuals 65 years of age or older, sociologists and physicians at the Wentworth Medical Center in upstate New York investigated the relationship between geographic location and depression. A sample of 60 individuals, all in reasonably good health, was selected; 20 individuals were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina. Each of the individuals sampled was given a standardized test to measure depression. Higher test scores indicate higher levels of depression. A second part of the study considered the relationship between geographic location and depression for individuals 65 years of age or older who had a chronic health condition such as arthritis, hypertension, and/or heart ailment. A sample of 60 individuals with such conditions was identified. Again, 20 were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina. Prepare a managerial report that summarizes…
Is College Worth It? In the New York Times article “College Graduates Fare Well in Jobs Market, Even through Recession,” C. Rampell noted that college graduates have suffered through the recession and lackluster recovery with remarkable resilience. Of a random sample of 1020 college graduates, 35 were unemployed; and of a random sample of 1008 high-school graduates (no college), 69 were unemployed. a. At the 1% significance level, do the data provide sufficient evidence to conclude that college graduates have a lower unemployment rate than high-school graduates? b. Find and interpret a 98% confidence interval for the difference in unemployment rates of college and high-school graduates.
