Question

Which of the following gives a description about standard and mean deviation.

• A. measures of dispersion which depends upon the deviations of observations from central tendency
• B. measures of central tendency of the given observations
• C. maximum and minimum values taken
• D. all of the above

Answer 1

The correct option is A

measures of dispersion which depends upon the deviations of observations from central tendency

Standard and mean deviation help us to visualize a rough idea of how the data is scattered or dispersed about the central tendency. Range tells us about difference in maximum and minimum values in the given set.
