What are the pros and cons of using the mode as your measure of central tendency? Solution The mode is that observation that occurs most often. It is usually not unique, and is therefore not that often used. Advantages : 1) It has the advantage that it applies to numerical as well as categorical variables. 2) As with the median, the mode is easy to find if the data is small and sorted. Disadvantages : 1) The mode only refers to the element that ocurs the maximum number of times. So, it doe snot apply when the data set has many outliers or if the data set has a very large number of elements.
