Mary has an interest in doing a study to see if 6th graders are affected by noise level on a math lesson. 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 for 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.
