What is the major drawback of non-probability sampling compared to probability sampling?
Reduced or limited generalizability
What is the difference between practical generalizability and statistical generalizability?
Statistical: must have random sampling, allows you to generalize to the population from which you randomly selected. Practical: do the results hold for similar individuals? allows you to generalize to similar individuals
What the methods being used in conducting a research?
Quota sampling stratified sampling random sampling convenient sampling cluster sampling semi stratified sampling stratified quota
Sampling in operations research and management?
semi stratified sampling
What is sampling in research?

Yes.
What are the merits and demerits of sampling methods?
Advantages and Limitation of Sampling: 1. Sampling saves time and labour. 2. It results in reduction of cost in terms of money and manhour. 3. Sampling ends up with greater accuracy of results. 4. It has greater scope. 5. It has greater adaptability. 6. If the population is too large, or hypothetical or destroyable sampling is the only method to be used. The limitations of sampling are given below: 1. Sampling is to be done by qualified and experienced persons. Otherwise, the information will be unbelievable. 2. Sample method may give the extreme values sometimes instead of the mixed values. 3. There is the possibility of sampling errors.
What are the reasons for choosing random sampling method for ones research work and what is random sampling method anyway?
because it is the simplest sampling technique which requires less time and cost.
What is sampling precision?
it implies the degree to which the strate choosen for research is apt
why do you use sampling design in research studies?
To avoid mistakes and correct
