Question

Quizplus · Accepted Answer

Experimental error refers to inaccuracies or variations that occur in the data collection process of an experiment due to unpredictable and uncontrollable factors. Poorly written questions, background noises, and the researcher falling asleep during measurement can all introduce variability or bias into the data, affecting the reliability and validity of the experiment's outcomes. However, a participant's body chemistry is not considered an experimental error but rather an inherent characteristic that could be a variable of interest in the study depending on the research question.
