Question

Quizplus · Accepted Answer

Outliers are a few values that are significantly higher or lower than most values in a distribution. They can distort the overall distribution and affect statistical analyses. A and B are incorrect because they only refer to the highest and/or lowest scores, whereas outliers can be present anywhere in the distribution. D is also incorrect because outliers can occur in any type of data, not just test scores.
