What Is a Sampling Error? A sampling error is a statistical error that occurs when an analyst does not select a sample that represents the entire population of data. As a result, the results found in the sample do not represent the results that would be obtained from the entire population....
Do note that there is an intrinsic trade-off betweentype 1and type 2 errors. The likelihood of a type 2 error increases when the likelihood of atype 1 errordecreases, and vice versa. It takes a careful assessment of the specific research setting, risk mitigation, potential outcomes, and ava...
