Answer-Which of the following is an example of non-random sampling?

Question

Accepted Answer

Non-random sampling involves methods where not every individual has an equal chance of being selected. In this case, choosing all students from one class is an example of convenience sampling, a type of non-random sampling. This approach is often faster and easier but can introduce bias, as the sample may not represent the broader population. For instance, a single class might share similar characteristics that dont reflect the diversity of the entire student body.   Why Other Options Are Wrong    A Systematic sampling is random, as every 10th customer is chosen systematically but without bias.   B Random number generation ensures random selection.   D Stratified sampling is a random technique that ensures proportional representation.   E A random number table is a classical random sampling method.
