An outlier is a data point that is significantly different from other observations in a sample or population. It can be either unusually small or unusually large. Option A, sample statistic, refers to numerical values calculated from a sample, such as mean, standard deviation, etc. Option B, median, is the middle value in a set of data when arranged in order. Option C, z-score, represents the distance between a data point and the mean in terms of the number of standard deviations. None of these options specifically refer to unusually small or large data values.
