Sampling Technique
Sampling The determination of sample size for processes is concerned with the following issues under the assumption that the characteristic of the population were more or less homogenous.
- The definition of the population
- The creation of sampling frame
- The choice of Probability versus Non-probability sampling
- The calculation of sample size
The creation of sampling frame: The standard rule for sampling frame has been followed based on SRS (Simple Random Sampling). The choice of Probability versus Non-probability sampling: Probability sampling has been followed.
The calculation of sample size: To determine the minimum sample size the following formula has been followed:
Where
- n=sample
- size z= statistical certainty chosen
- p= coverage rate/estimated prevalence q=1-p
and
- d= precision desired
