Answer #1

A major weakness of non probability sampling is (a). Low internal validity.

Non-probability sampling is a sampling technique where the odds of any member being selected for a sample cannot be calculated. It’s the opposite of probability sampling, where you can calculate the odds.

It can be seen that in non probability sampling, we can't know how well the sample represents the population. So we can't rely on the validity of the sample chosen. Also we can't calculate confidence intervals and margin of errors in non probability sampling.

PART 1: Sampling How we select our sample will directly influence the external validity of the study. If a sample is representative, then our external validity is stronger. If a sample is non-representative, then our external validity is weaker. QUESTIONS: 1.
