In this data set, the presence of an outlier (95) significantly affects the mean (average). The mean is calculated by summing all values and dividing by the total number of values. Because the mean is sensitive to outliers, it may not accurately represent the central tendency of the data set in this case.
The median, however, is not as sensitive to outliers. It represents the middle value when the data set is arranged in ascending or descending order. In this case, when we arrange the data set in ascending order, the median would be the third value, which is 3. Therefore, the median would be the best measure of central tendency for this data set.
