• Mean, Variance & Standard Deviation

  Part 2

  In this S1 session, discussion of the chapter Representation of Data is continued.

  Calculation of the Mean, Variance and Standard Deviation (Part 2) of a distribution of data is explained.

  You will learn about the following:

  ♦ The Mean, Variance & Standard deviation of Tabulated Individual Data

  ♦ The Mean, Variance & Standard deviation of Grouped Data

  ♦ Combining 2 or more sets of data

  ♦ Data containing Assumed Mean (D)

  ♦ Examples

   

  Notes and Homework are available at the Exercise section of this session
