Of course, the probability is most popular due to its generalizability but it depends upon number of criteria that which type of sample is appropriate, Probability or Non probability.
There are different types of sampling probabilities. It is most important point that which kind of sample probability is fit for analysis. For this we take and screen the data and then we decide the appropriate kind of probability.
There are five most relevant points of criteria to help us for choosing the appropriate sample.
1- Degree of accuracy
2- Recourses
3- Need of statistical Analysis
4_ National Vs local project
Conclusion:
If these 5 numbers of criteria required and want the Accuracy, generalization sampling arid calculation then we apply some statistical test and choose the probability sample because it is:
1- More reliable and authentic
2- Cost has less value and accurate result
3- There is no single prediction for the whole project
4- Results give large change
5- Initial result will be acceptable for other research
If non accuracy, unlimited resources and hidden knowledge of population are given and no need of perfection, then we choose the non-probability sample.
