What difference between Statistical Sampling and non statistical sampling?
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
What are the disadvantages of non probability sampling?
It is quite likely that the sample is not representative of the population and so while statistical conclusion may be valid for the sample, they may not apply to the population.
Why its is necessary to use sampling in statistical investigation?
Sampling gives good insight of the choosen sample
What are the disadvantages of systematic sampling?
Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.
Disadvantages of sampling?
Sampling has several disadvantages. These include time consuming and tedious. Possibly, members of units are different from one another, thus decreasing its effectiveness.
