4. Systematic Sampling-

●     Also known as Shortcut method of random sampling

●     Units of the population are arranged - Numerically, geographically or alphabetically

○     you randomly select a starting point

○     From there onwards, every Kth person on the list is selected

 

●     Population = 100 students ●     10 are to be selected ●     All 100 students would be numbered and systematically arranged ●     If the first randomly selected number is 5th Item, Then the subsequent numbers would be 15th 25 35 45 55 65 75 85 and 95th Item.

 

Merits-

●     Very simple method, sample is easily determined

●     Hardly any possibility of personal bias

 

Demerits-

●     Because only first item is selected on random basis, every item in the population does not get equal chance of being selected

●     This method serves no specific purpose if all the items in the population are homogeneous.
