Quizplus · Accepted Answer

Regression to the mean occurs when extreme scores or values are more likely to move towards the average on subsequent attempts. In the scenario given, the initial high score was likely due to chance and not necessarily reflective of the individual's true ability. Therefore, on subsequent attempts, the individual is more likely to score closer to their true average performance. This is a threat to internal validity as it can affect the accuracy and validity of the results when studying a particular variable or phenomenon.
