Case studies provide an in-depth look at a specific instance or phenomenon, making them useful for qualitative analysis. They can involve various data sources, including interviews, documents, and observations, to build a comprehensive understanding of the subject. This method is particularly effective in fields like psychology, business, and education.
When conducting a case study, focus on a well-defined case that illustrates broader trends or issues. Limitations include potential biases and challenges in generalizing findings, so it’s often beneficial to use multiple case studies for comparative analysis.
Experimental Design
Experimental design involves manipulating one or more independent variables to observe their effect on a dependent variable, allowing for causal inferences. This method is commonly used in fields such as psychology and medicine. Key components include randomization, control groups, and replication to enhance reliability.
When planning an experiment, clearly define your hypothesis and choose appropriate measures for your variables. Ensure ethical considerations are addressed, especially in human subjects research, and aim for a sample size that provides sufficient power to detect meaningful effects, typically in the range of dozens to hundreds, depending on the expected effect size.
