Non-experimental research means studying topics as they exist without manipulating any variable or assigning participants to different conditions. The aim is to describe characteristics, conditions, or outcomes rather than test cause-and-effect. Descriptive research captures this best because it focuses on describing what is present in a population or phenomenon—providing a snapshot of features or statuses without intervention. While correlational or ex post facto designs also fall under non-experimental methods and look at relationships between variables, they aren’t as general a description of what non-experimental work aims to do as descriptive research. Cross-sectional designs are common non-experimental approaches that collect data at one point in time, but that describes a timing aspect rather than the overarching goal of describing what exists.
