Ex-post facto research and experimental research are two distinct approaches commonly used in psychological research, each with unique features, purposes, and limitations. Understanding the differences between these two methods is essential for selecting appropriate designs based on the research question, ethical considerations, and feasibility. Ex-post facto research, also known as causal-comparative research, investigates the possible cause-and-effect relationships by observing an existing condition or behavior and looking backward to identify potential causal factors. In this method, the researcher does not manipulate any variables. Instead, groups are formed based on naturally occurring differences, such as gender, socioeconomic status, or clinical diagnosis, and the researcher studies how these variables relate to outcomes. This method is often used when experimental manipulation is either unethical or impractical. For example, _______ _______ ______ __________ ______ ______ ___ __________ _____.
