Sampling error can be reduced by
Sampling and Non sampling errors
Pros and Cons of a non-probability sampling
There can be no set value. An acceptable level of sampling error for a company making high precision machine parts is likely to be very different from the sampling error for household incomes, for example.
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
In stats, a sampling error is simply one that comes from looking at a sample of the population in question and not the entire population. That is where the name comes from. But there are other kinds of stats errors. In contrast, non sampling error refers to ANY other kind of error that does NOT come from looking at the sample instead of the population. One example you may want to know about of a non sampling error is a systematic error. OR Sampling Error: There may be inaccuracy in the information collected during the sample survey, this inaccuracy may be termed as Sampling error. Sampling error = Frame error + Chance error + Response error.

Sampling error leads to random error. Sampling bias leads to systematic error.
Sampling error can be reduced by
ome suggested ways: Larger samples, Better sample design, Better measurement, Better data validation, Better survey/questionnaire design.
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
a sampling error is o ne that occurs when one uses a population istead of a sample
The sampling error is inversely proportional to the square root of the sample size.
Answer is Quota sampling. Its one of the method of non-probability sampling.
The major source of sampling error is sampling bias. Sampling bias is when the sample or people in the study are selected because they will side with the researcher. It is not random and therefore not an adequate sample.
Sampling and Non sampling errors
Sampling error occurs when the sampling protocol does not produce a representative sample. It may be that the sampling technique over represented a certain portion of the population, causing sample bias in the final study population.
