The selected 60 random variables out of 2002 random variables are collected. The
option “Random Variable Generation” of “Data Analysis” toolpack is used for extracting
random variable.
Task 2:
Quantitative Variables:
Order Quantity

Median 32
Mode 39
Standard Deviation 13.09171256
Variance 171.3929379
Minimum 2
Maximum 50
Range 48

(Oja 1983)
The average value of the Order Quantity is 30.11667 with standard deviation 13.0917
and variance 171.3929. The maximum order quantity is 50 and minimum order quantity is 2
with the range 48. The calculated coefficient of variation is 43.4699%. The location
parameters show that 1st quartile, median (2nd quartile) and 3rd quartile values of order
quantity are 19, 30.11 and 40.25. The inter quartile range is found to be 21.25. The Order
Quantity of number 32 is maximum in frequency.
