More about Measures of Central Tendency (English subtitles available)

The relative merits of different measures of central tendency for a given situation are first introduced. The emcees explore and make conjectures on the effect of the central tendency of the data when a certain item is removed from or added to a dataset. Also, they keep exploring the effect of the central tendency of the data when adding or multiplying the whole set of data by a common constant. Finally, the effect on the central tendency of the data is discussed when zero is inserted into the dataset.
