Can I please get help with #1 & #2 on my practice work sheet for better understanding?
l. A researcher is interested in the effect of music on memory for words. He recruits a sample of students and assigns them to one of three different types of music - country, pop, and emo. He has them listen to the assigned music through headphones while they are shown a list of words. At the end of a given amount of time, they have to type of the words into a GoogleDoc. The words are checked against the words given to be scored for accuracy. The scores are in the table below 7 note that each score represents one person: Country Music Group I Pop Music Group Emo Tunes Group 3 | 5 9 2 | 3 e 5 | 5 9 2 I 2 7 2 9 The research finds that the SS, is 104.88 and the 55h is 16.74. Using that information and the information in the chart above. Complete the ANOVA chart below you will need all the answers to complete the Assignment #9 quiz. 7 Source l SS d'f MS ' F Between ' ' Within l 16.74 ' l Total 104.88 , l t a. Now, using the degrees of freedom you found and the Fcritical chart, find the F -critical to be used for comparison: b. Given the F -critical that you found, is there a statistically significant difference in these conditions yes or no? 2. SPSS Interpretation: Use the study blurb below and the image of the SPSS output to answer the following questions: You are a researcher interested in the effects of distraction on task performance. You recruit participants and assign them to one of three groups. Group 1 had participants listen to loud music while completing a logic puzzler Group 2 had participants complete the logic puzzle in a room with a television that remained constantly which was tuned to CNN. Group 3 had participants complete the puzzle in a quiet room. All participants were timed on how quickly they completed the puzzle in minutes. The researchers hypothesized that the participants in the quiet room would complete the puzzle the fastest. You plug your data into SPSS and run a oneway ANOVA.
