What is the primary goal of random assignment in experimental research?

Balance individual differences variables across conditions.
Hold conditions consistent across conditions.
Make sure the dependent variable does not differ across conditions.
Select different levels of a natural groups variable.

The correct answer is: Balance individual differences variables across conditions.

The primary goal of random assignment in experimental research is to balance individual differences variables across conditions. By randomly assigning participants to different groups or conditions, researchers aim to ensure that any pre-existing differences among participants are equally distributed. This process minimizes the impact of confounding variables, which can affect the experimental outcome. As a result, the internal validity of the study increases because it isolates the effects of the independent variable on the dependent variable, allowing any observed effects to be attributed to the manipulation rather than other factors. In this context, balancing individual differences is crucial for achieving reliable and generalizable results from the experiment. This approach helps researchers draw more accurate conclusions about cause-and-effect relationships within the study.
