Question

Quizplus · Accepted Answer

The mean is most impacted by the presence of the outlier value (32) because it is calculated by adding all values and dividing by the number of values, making it sensitive to extreme values. The median and mode are less affected by outliers; the median is the middle value when data are ordered, and the mode is the most frequently occurring value(s).
