Business Statistics

Basis

Dispersion

Skewness

Nature

Shows the spread of values from the central value

Shows whether series is symmetrical                       or asymmetrical.

Basis

It depend upon the averages of second order.

Depends upon the averages of first and second order.

Relationship with moment

Based     on     all                three moments

Based on first and third moment only.

Variability

Study of the Variability

Study of concentration in lower          and          higher variables.

Diagrammatic presentation

Cannot be presented by means of diagrams & graphs.

Skewness           can          be presented by diagram.

Inference

All     the    measures    of dispersion are positive.

Coefficient of skewness can be positive or negative.
