Answer:
For calculating the coefficient of quartile deviation, the formula applied is.
Q3−Q1/ Q3+Q1
Question 7
Define mean deviation.
Answer:
A mathematics average of the deviations of all the principles taken from some average value (mean, median, mode) of the series, ignoring signs (+ or -) of the deviation is mean deviation.
Question 8
What is standard deviation?
Answer:
The square root of the arithmetic mean of the squared deviations of the items from their mean value.
Question 9
What is a Lorenz curve?

Lorenz curve is a curve that shows the actual distribution deviation (of income or wealth) from the line exhibiting equal distribution.
