Question

What would be an example of an experimental design involving manipulation?

Answer 1

Example of an Experimental Design involving manipulation:

Step 1:

Let the research question be:

Does music in the background improve the performance of a student?

Step 2:

Randomly assign the n volunteer students to one of the two mutually exclusive groups:

Group 1: Exprimental Group: Students studying with music in the background

Group 2: Control Group: Students studying without music in the background

Step 3:

Evaluate the performance of each student by a test after the experimentation and tabulate their scores in the test

Step 4:

Conduct a Two Independent Samples t test to find out whether the performance of the student is significantly higher for studying with music in the background as compared to studying without music in the background.

Explanation:
In the above experimentation for answering the research question, "Does music in the background improve the performance of a student?", the researcher manipulates the Independent Variable: with or without music in the background in order to study its effect on the Dependent Variable: the performance of the student.
