What would happen to the variance of a data set if we added 5 to every observation?

Which information is false regarding Lorenz curve

A good dispersion should have following characteristics except

While drawing Lorenz curve zero of X-axis and 100 on Y-axis are joined by a line. This line is known as

The variance

What would happen to the variance of a data set if we multiplied every observation by 5?

Following are the Relative measures of dispersion except

The degree of variation among the values  is evaluated by various measures of ---------------

A measure of relative dispersion is given by the:

Quartile deviation is calculated by

The standard deviation of ungrouped data can be calculated by:

Square of standard deviation is called

There are two types of measures of dispersion

Absolute measures of dispersion are

The average of the squared deviations from the arithmetic mean is called the

The main disadvantage of the standard deviation is

The inter quartile range

The number of protozoa seen under 5 separate microscope slides were 3,4,5,6 and 7. The sum of squared deviations of observations from their sample mean is:

The _______________ is the easiest measure of dispersion to calculate.

Half of the difference between the first and third quartiles

In case of open-ended classes, an appropriate measure of dispersion to be used is

the positive square-root of the arithmetic mean of the Square of the deviations of the given observation from their arithmetic mean is called

Formula given below is used to calculate

Standard deviation is also called

The heights in cm of a group of first year biology students were recorded. The variance of these heights was subsequently calculated. The unit of measurement for this variance is:
