Question

Quizplus · Accepted Answer

The majority of the scores being low (45 or below) and only a few students performing well indicates a tail that extends towards the higher values, resulting in a positively skewed distribution. A normal distribution would have a roughly symmetrical shape, and a negatively skewed distribution would have a tail extending towards the lower values. Nominal refers to a type of categorical data, which is not relevant in this context.
