Question

A researcher wants to study the effect of different levels of noise on the performance of students in a math test and a history test. The two levels of noise are low and high. The researcher uses different sets of individuals for each level and each type of test. This is an example of a(n):_______.

Answer 1

independent groups design.

Step-by-step explanation:

In independent groups design, the researchers will put different subjects/participants for each different tests on the research. (this is why the students are separated to low level group and high level group.)

Typically, this type of study is being done to find for two reasons:

1. To find out a how different external occurrences can influence the condition of a certain variable.

2. To accelerate the research process. Separating the group will be faster compared to testing each test one by one.
