Experimental research involves manipulating one variable to determine if changes in one variable cause changes in another variable. This manipulation includes controlling the selection of participants and dividing them into groups (e.g., experimental vs. control groups). Causal-comparative research, on the other hand, does not manipulate variables but rather investigates the cause-effect relationship between variables as they naturally occur.
