D)Experimental error can be caused by weak manipulation of the independent variable.

Question

Quizplus · Accepted Answer

Experimental error refers to the variability in data that arises from the experimental setup and execution, not the strength of manipulation of the independent variable. Weak manipulation of the independent variable might lead to a failure to detect a true effect (increasing the risk of a Type 2 error), but it is not considered an experimental error in itself. Experimental errors are more about inaccuracies or variations in measurement, data collection, or experimenter influence, rather than the conceptual design aspects like the strength of the independent variable's manipulation.
