  1.   Part One of Problem: Teacher Jones is planning a study to see if learning of 8th graders on an algebra lesson is affected by background noise level. He wants to use a t-test for independent groups to analyze her results. What is his independent variable? Describe two conditions he could create for the independent variable in his study. What is his dependent variable? Describe a way to measure the dependent variable so that each participant would have one score at the end. Would this dependent variable measure be on a continuous scale of measurement? Why is this important? Explain and justify.

 

  1. Part Two of Problem: Consider Teacher Jones’ experiment regarding whether learning of 8th graders on an algebra lesson is affected by background noise level. Teacher Jones has collected his data. What is the null hypothesis for his study? What is the alternative hypothesis for his study? What are the assumptions that must be met about his data before he can correctly use an independent t-test to test the hypotheses? Why? How would he see if his data met these assumptions? How much room does he have to violate any of these assumptions and still get accurate results from the t-test? Explain and justify.

 

  1. Part Three of Problem: Teacher Jones interest in doing a study to see if learning of 8th graders on an algebra lesson is affected by background noise level. There, he was planning to use two noise conditions and then analyze his outcomes using a t-test for independent groups. Describe the study Teacher Jones might plan where he would use a one-way analysis of variance (ANOVA) for independent groups instead of a t-test to study differences between noise levels. What is his independent variable? Describe the conditions he could create for this study. What is his dependent variable? Describe a way to measure the dependent variable so that each participant would have one score at the end that would be on a continuous scale of measurement. Explain and justify.

 

 

  1. Part Four of Problem: Consider Teacher Jones study of whether the learning of 8th graders on a algebra lesson is affected by background noise level. Describe the pros and cons of Teacher Jones using a repeated measures design for this study. What would you probably choose to do? Explain and justify
