Question

Consider the strengths and limitations of descriptive, correlational, quasi-experimental, and experimental studies. Discuss each one.

Answer 1

Strengths and limitations of

the descriptive study;

Strengths;

• it provides a multifaceted approach for data collection so that it help us to give a broader view of the information.

Limitations;

• it can relate to human error in the collection of data.

Coorelational studies'

Strengths;

• it opens up a great deal of further research to other scholars.
• it allows the researcher to determine the strength and direction of a relationship which helps the later studies to narrow down.

weakness;

• it only uncovers the relationships
• it won't determine which variable have the most influence
• time-consuming process
• an extraneous variables may interfere with the information.

Quasi-experimental studies;

Strengths;

• less time consuming
• less expensive
• can be strenghtened with control groups
• can retrospectively analyse the chnages

weakness

• often incomplete
• difficult to obtain
• not randomised

Experimental studies

Strenghts;

• reseacher have control over variables
• humans perform the experiments
• can be combined iwth other research methods
• use to determine what is best for the population
• provides for greater transferability

weakness'

• chance of occurence of personal bias
• sample may not be representative
• can produce artifical results
• groups may not be comparable
• human response can be difficult to measure
