• Box-and-whisker Diagram

  (Representation of Data)

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

  The Box-and-whisker diagram method of Representation of Data is explained with examples.

  You will learn about the following:

  ♦ The Boxplot

  ♦ Skewness of Distribution of data

  ♦ Boxplot for Symmetrical Distributions

  ♦ Boxplot for Positively Skewed Distributions

  ♦ Boxplot for Negatively Skewed Distributions

  ♦ Relationship between Mean, Mode and Median deduced from Boxplot

  ♦ Outliers and how to calculate the lower and upper bounds for outliers using Boxplot

  ♦ Examples

   

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