Question if you would like??
1. In Module 4, we considered Mary's interest in doing
a study to see if learning of 6th graders on a math lesson is affected
by background noise level. There, she was planning to use 2 noise
conditions and then analyze her outcomes using a t-test for independent
groups. Describe the study Mary might plan where she 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 her independent
variable here? Describe the conditions she could create for this study.
What is her dependent variable? Describe a way to measure the DV so that
each participant would have one score at the end that would be on a
continuous scale of measurement. Support your responses.250 words plus referenceWeek 6.docx2. Consider Mary's study of whether the learning of 6th graders on a math
lesson is affected by background noise level. Describe the pros and cons
of Mary using a repeated measures design for this study. What would you
probably choose to do? Support your responses.250 words plus reference
