What is Central Tendency?

A central tendency is a central or typical value for a probability distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s. The most common measures of central tendency are the arithmetic mean, the median, and the mode.

Here, Given data

   x                             f                     xf

  5                             1                       5

  6                             4                      24

  7                             3                       21

  8                             2                       16

  10                           2                        20

  13                            2                        26

   14                           1                         14

Mean = ∑xf/∑f

         = 126/15    

         = 8.4

Median = 7

Mode = 6

Thus, Mean, median, and mode of the given data is 8.4, 7, and 6 respectively.
