Expert Solution

Measures of central tendency in statistics refers to the 'single number' or 'typical value' that represents a probability distribution. Often called the averages, measures of central tendency try to point to the approximate centre of the distribution. Each of the multiple measures of central tendency serves a specific purpose and is used in an appropriate context. 

Commonly used measures of central tendency include: mean, median and mode.

Measures of dispersion in statistics refers to the scattering of data. Also, called measures of variation, these indicate the extend of spread of observations around these "central" values in a distribution. Thus, data  variability is what is pointed to by these measures. 

Commonly used measures of dispersion include: variance, standard deviation and quantiles.

Measures of central tendency in statistics refers to the 'single number' or 'typical value' of a probability distribution.  Measures of dispersion in statistics refers to the scattering of data around these "central" values.
