Measure of Dispersion

The tendency of the values of a variable to cluster around a central vale is known as :

• dispersion
• central tendency
• range
• standard deviation

If the lorenz curve coincides with egalitarian line then income inequality will be :

• highest
• lowest
• moderate
• immmeasurable

The difference between the highest value and the lowest value of the variable is _________________.

• mean
• median
• range
• standard deviation

The square of the standard deviation is known as ___________.

• variance
• range
• coefficient of variation
• median

If all the observations are equal their standard deviation will be _________________.

• constant
• 1
• zero
• equal to the value of the observation
