Explanation
The scores of the three students who score much differently from the rest of the class are known as outliers or extreme scores. The mode is the most frequently occurring score in a distribution. Even though outliers skew a distribution, they are not called skewers. Variance is a measure of the variability in a distribution as is standard deviation.
