Case Study vs Experiment
Case study and experiment, having a definite difference between them, refer to two very different research methods used in various disciplines. These research methods allow the researcher to study and analyze the subject through various approaches. Having a variety of methods in research allows the researcher to gain both qualitative and also quantitative data. He is also able to cross check the data, through which he will be able to assign more validity to the conclusions and overall findings of the research. A case study is a research method in which the researcher explores the subject in depth. The case study can be about an individual, a special phenomenon, a place of specific significance, etc. On the other hand, an experiment refers to a research method where there are two specific groups or else variables that are used to test a hypothesis. This highlights that case study and experiment are different from one another. Through this article let us examine this difference further.
What is a Case Study?
As mentioned in the introduction, a case study is a method where an individual, an event, or a place of significance is being studied in depth. To be more elaborative, in the case of an individual, the researcher studies the life history of the individual. This can include important days, special experiences of the individual. The case study method is used in a number of social sciences such as sociology, anthropology, psychology, etc.
Through a case study, the researcher can identify and comprehend the subjective experiences of an individual regarding a special topic. For an example, a researcher who studies the impact of second rape on the lives of rape victims can conduct a few case studies which will allow him to comprehend the subjective experiences of the individuals as well as social mechanisms that contribute towards this phenomenon. The case study is a qualitative research method that can be subjective.
What is an Experiment?
An experiment, unlike a case study, can be categorized under quantitative research, as it provides statistically significant data as well as an objective, empirical approach. Experiments are used mostly in natural sciences as it allows the scientist to control the variables. In the social sciences, this can be rather tricky because controlling variables can contribute towards faulty conclusions.
In an experiment, there are mainly two variables. They are the independent variable and the dependent variable. The researcher tries to test his hypothesis by manipulating the variables. When speaking of experiments, there are different types, such as laboratory experiments (which are conducted in laboratories where the conditions can strictly be controlled) and natural experiments (which take place in the real life setting).
As you can observe, case study method and experiments are very different from one another. However, most researchers prefer to use triangulation when conducting research to minimize biases.
What is the Difference Between Case Study and Experiment?
Definitions of Case Study and Experiment:
Experiment: An experiment refers to a research method where there are two specific groups or else variables that are used to test a hypothesis.
Case Study: A case study is a research method in which the researcher explores the subject in depth.
Characteristics of Case Study and Experiment:
Experiment: In an experiment, there are two variables, one independent variable, and a dependent variable.
Case Study: In a case study, the above feature cannot be explored as it is not testing the correlation between two variables
Experiment: In an experiment, a hypothesis is being tested to proof the correlation between two variables.
Case Study: In a case study it is not so; it only explores a subject in depth.
Manipulation of Variables:
Experiment: An experiment involves manipulating the variables to test the hypothesis.
Case Study: In a case study it is not so, as it is not testing any hypotheses.
Experiment: An experiment mostly provides quantitative data.
Case Study: A case study provides qualitative data.
Experiment: Experiments are used in natural sciences.
Case Study: Case studies are mostly used in social sciences.
