Chapter 1: Problem 7

What are the advantages and disadvantages of the case study, correlational method, and experimental method? pp. 21-30

Short Answer

Expert verified

Case study, correlational, and experimental methods each have their strengths and weaknesses. While case studies provide in-depth data, they lack generalizability. Correlational research can determine relationships between variables naturally, but can't establish cause and effect. Experimental methods can establish cause and effect but may lack ecological validity.

Step by step solution

Define Each Method

Begin by defining each research method: The case study method involves the in-depth study of a single subject or a small group. Correlational research examines the relationship between two variables without manipulation. The experimental method manipulates one variable to determine its effect on another variable.

Identify Advantages of Each Method

Following the definitions, identify the advantages of each method. The case study's key advantage is the depth of data gathered which helps to uncover complexities in behaviour that may not be understood through other research methods. Correlational research's advantage lies in its ability to study the relationship between two variables as they naturally occur. For the experimental method, this ability to control and manipulate variables allows for the establishment of cause-and-effect relationships.

Discuss Disadvantages of Each Method

Lastly, discuss the disadvantages of each method. Case studies are often criticized for their lack of generalizability, due to small sample sizes and potential researcher bias. Correlational research, meanwhile, cannot establish cause-and-effect relationships. Experimental methods, though immensely powerful, are often criticized for a lack of ecological validity, as manipulations to variables may not reflect real-world contexts.
