Question
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.Mary's interest in doing a study to see if learning of 6th graders on a math lesson is affected by background noise level.

Explanation / Answer
An independent variable is usually varied to determine the effects thus it is the presumed cause. The researcher usually has control over the variable. The Independent variable (IV is the Background noise level.
Describe two conditions she could create for the IV in her study.
Conditions are the treatments or the repeated measures that are essential for testing how they impact the dependent variable.
Condition A= Very loud background noise level
Condition B= low background noise level
What is her dependent variable (DV) here?
The dependent variable is the measured response. It can be termed as the presumed effect that is measured through the manipulation of the independent variable (Bryman, 2012). The dependent variable thus is the learning of 6th graders on a math lesson that is measured through two possible conditions.
Describe a way to measure the DV so that each participant would have one score at the end. Would this DV measure be on a continuous scale of measurement? Why is this important? Explain and justify.
The learning of the 6th graders on a math lesson will be measured through the exposure to both very loud background level noise and low background level noise. The learning of the 6th graders will be measured through the level of understanding of the learned material with the different exposures to the conditions for the independent variable. The 6th graders will be subjected to a test concerning the learned material.
The results will be the different scores by the students. The scores for the dependent variable, thus, will be measured on a continuous scale of measurement. There will be intervals of the student scores that are measured by a total of 100%.
Use of continuous data through the intervals justifies the use of easy statistical techniques like the mean. The data can also be easily recorded at numerous points. For this reason, it will be easier to analyze the data through the use of a t-test
