Sampling is the process of selecting a representative subset of a population to determine characteristics of the whole population. It involves 7 steps: defining the population, identifying the sampling frame, specifying the sampling unit and method, sample size, sampling plan, and selecting the sample. Sampling provides advantages like being economical, faster, allowing for more comprehensive information, and greater accuracy than a complete enumeration. There are two main types of sampling - probability sampling which includes simple random, systematic, and stratified sampling, and non-probability sampling which includes convenience, judgement, and quota sampling.

2. Meaning


In other words, the process of selecting a
sample from a population using special
sampling techniques called sampling.

3. Sampling Process







Step 1:Define the population
Step 2:Identify the sampling frame
Step 3:Specify the sampling unit
Step 4:Specify the sampling method
Step 5:Specify the sample size
Step 6:Specify the sampling plan
Step 7:Select the sample

4. Advantages of Sampling





It is economical and practical
Faster and cheaper
It can yield more comprehensive information
It is more accurate
The sample survey makes possible the use of
much larger and much more varied
populations than would be possible for the
same expenditure if one were making a
complete enumeration.
