Final answer:
The extent to which a causal relationship found in a study can be expected to be true for the entire target population is called generalizability. It refers to the ability to apply study findings to a larger population beyond the sample that was studied.
Step-by-step explanation:
The extent to which a causal relationship found in a study can be expected to be true for the entire target population is called generalizability. Generalizability refers to the ability to apply study findings to a larger population beyond the sample that was studied. It is important for researchers to use random sampling and random assignment methods to increase generalizability and ensure that the results can be applied to the target population.
