    Mean = sum of observations divided by the number of observations. Mode = the observation that occurs most frequently. Median = value of the middle observation if uneven number of observations, or the average of the two middle if even number of observations

    Median = value of the middle observation if uneven number of observations, or the average of the two middle if even number of *sorted* observations ;)
