Answer 1: True Experimental Method Answer 2: of the use of random assignment. Answer 3: Study environment Answer 4: Quiet room, classical music, background noise Answer 5: Exam performance Answer 6: Ratio Dr. Johnson is investigating the effects of different types of study environments on exam performance. She randomly assigns 90 undergraduate students into three groups. The first group studies in a quiet room, the second group studies in a room with background classical music, and the third group studies in a room with background noise (e.g., people talking, traffic sounds). After an hour of studying, all students take the same standardized exam to measure their performance. Dr. Johnson wants to determine if the study environment affects exam scores. Study Design: This is a [Select] [Select] Independent Variable (IV): [Select] Levels of the Independent Variable (IV): [Select] Dependent Variable (DV): [Select] using the [Select] Scale because which is measured

In one image it shows the answers I picked for each box. it says I got some or one of them wrong but I’m not sure which. I will list down the answer choice options for each box.  Please help!! Thank you

Study Design:

- Correlational Method

- True Experimental Method

-Quasi-Experimental Method

Because:

- Of the use of random assignment

- We are assessing a relationship without manipulation

- The independent variable is made up of predefined groups 

Independent Variable:

- Number of students

- Type of exam

- Study environment 

- Time spent studying

Levels of the Independent variable

- Undergraduate students and graduate students

- Quiet room, classical music, background noise

- Low, Moderate, and high exam scores

- exam scores and study time

Dependent Variable:

- background noise levels

- time allocated for studying

- type of study environment

- Exam performance

Which is measured using the ___ Scale:

- Ordinal

-Nominal

- Ratio

- Interval

Answer 1: True Experimental Method Answer 2: of the use of random assignment. Answer 3: Study environment Answer 4: Quiet room, classical music, background noise Answer 5: Exam performance Answer 6: Ratio
