Question 1185hard
Which of the following statements relating to the sampling theory are correct?
1. The values of the statistical measures based on the sampled units are called values of statistics.
2. In the simple random sampling technique, the element of the population and the unit of the sample are different.
3. Snow-ball sampling technique is a probability based sampling technique.
4. The 'law of statistical regularity' and the 'law of inertia of large numbers' are the main bases of the sample to become representative of the population.

Question 1187hard
Assertion (A) Range is not useful to manager for comparison, if the observations are in different units.
Reason (R) For the purpose of comparison a relative measure of range is required which is called coefficient of range.
