The mean is 7.7, the median is 7.5, and the mode is seven. Of the three statistics, the mean is the largest, while the mode is the smallest. Again, the mean reflects the skewing the most. Generally, if the distribution of data is skewed to the left, the mean is less than the median, which is often less than the mode.

WebbIn practice, we can estimate the skewness in the population by calculating skewness for a sample. For the sample, we cheat a little by assuming that the random variable is uniformly distributed, so the probability of each y_i in the sample is 1/n and the third, central, sample moment becomes 1/n times a simple summation over all (y_i —y_bar)³.
