Final Lab Exercise 12/2/2022 Follow along and write down your answers to the questions during the lab section. Then submit this document under “Lab Bonus” portal “Final Lab Bonus Points for Final Exam”. If in 8 am section, submit this document by 10:30 am, if in 2 pm section, submit this document by 4:30 pm. No need for detailed responses. In this dataset, the first IV is: Music Condition The levels of the first IV are: placebo (people don’t listen to music) and classical music (people listen to classical music) The second IV is: The levels of the second IV are: The first DV is: Math task performance The second DV is: Reading task performance Q1 Reported Sample Statistics Reported Test Statistics What type of analysis is shown above?
- This is a one-sample t-test What is the hypothesis/ question tested? - Is the math performance of the 50-participant sample significantly different than a test score of 35? How would we report the results of this test? - T-statistic: t (49) = -3.93, p <.001 What is the Confidence Interval around the mean difference telling you? - That the math performance scores were significantly lower than the test value of 35 since the intervals didn’t contain 0 and were all negative. What do we conclude from these statistical results? - That the math performance scores of the 50-participant sample were significantly lower than the test value of 35. Q2 Reported Sample Statistics Reported Test Statistics What type of analysis is shown above? - Independent sample t-test What is the hypothesis tested?
- Is the math task performance in the placebo condition significantly different than the math task performance in the classical music condition? How would we report the results of this test? - The results indicate that there is a significant difference between the placebo condition ( M =25.04, SD =7.786) and the classical music condition ( M =34.76, SD =7.854) in math task performance, [ t (48) = -4.394, p <.001). What is the Confidence Interval around the mean difference telling you? The 95% confidence interval of the difference between means ranged from (-14.167 to -5.273) and indicates a significant difference between the means of the sample as there is no 0 between the intervals. What do we conclude from these statistical results? - Classical music group’s math task scores are significantly higher than the placebo group Q3 What type of analysis is shown above? - Pearson Correlation What is the hypothesis tested? - Is there a significant correlation between math task and reading task performance? How would we report the results of this test? - r = .42, p = .002 What do we conclude from these statistical results? - There is a significant positive correlation between math task performance and reading task performance.
