Question

A group of researchers wanted to explore if the type of studying strategies that students use is related to exam scores for high school students in India. The researchers collected data from 1000 high school students enrolled in introductory biology courses from each of the major cities across India. In the study, all students were exposed to the same material about brain cells once in class. Then, students were randomly assigned to: (1) re-read their notes three times across 3 days or to (2) organize their notes onto visuals of the brain cells in 3 sessions across 3 days. After 2 months, all students were given the same test about brain cells.
What kind of study design does this study on college students best represent?
a. Descriptive
b. Correlational
c. Experimental

Answer 1

Answer:

c. Experimental

Explanation:

Experimental study or research design: In research, the term "experimental study or research design" is often considered as a standard study design. In the experimental research design, one or more than one dependent variables or subjects are being randomly assigned to distinct treatments, i.e., the "independent variables" are being manipulated by the investigator or researcher and the results of the experiment are generally observed to make a conclusion.

In the question above, the given statement represents the "experimental study design".
