Driving Errors Across Developmental Age Groups: A One-Way ANOVA Study

Abstract

Week 5 Assignment: One Factor ANOVAs Written Response Worksheet NAME: Instructions: Follow along with the step-by-step instruction manual provided for the Week 5 Assignment. The instruction manual will make specific reference to data interpretation questions that require written responses. Use this worksheet to answer these written response questions. Each question is listed below along with the number of points each question is worth toward the assignment. Type your response in the space provided below each question. PART I: One-Way Between-Subjects ANOVA QUESTION 1 3 points Write out the null and alternative hypothesis for the one-way between-subjects ANOVA examining if developmental age group has an effect on the number of driving errors committed when a same-age peer is watching. Null Hypothesis: Alternative Hypothesis: QUESTION 2 3 points Examine the variability measures and the Levene’s Test for Equality of Variances. Based on these test results, does our data have problems meeting the equality of variance assumption? Should we consider using an alternative test such as the Welch or Brown-Forsythe to interpret the results of the test? QUESTION 3 3 points What were the results of the one-way ANOVA? Indicate whether the test was statistically significant or not, state whether you would reject or fail to reject the null hypothesis, and report the F-ratio results in statistical notation. QUESTION 4 3 points Use your one-way between-subjects ANOVA output to calculate the effect size eta-squared (). Report and interpret this effect size below. QUESTION 5 3 points Interpret the results of the Tukey HSD post hoc test. In your response, indicate which developmental groups are significantly different from each and explain how they are different from one another. QUESTION 6 8 points Write a brief one-paragraph report in APA Style summarizing the results of the study in Part 1 of your assignment. Report the ANOVA results in correct statistical notation, include a measure of effect size, and interpret the post hoc test results. Finally, provide at least...
