2.To avoid bias

3.No answer text provided.

4.To systematically favors the correct choice over every other choice on each question

Answer 1

We use random sample to avoid bias.

Many dissertation supervisors advice the choice of random sampling methods due to the representativeness of sample group and less room for researcher bias compared to non-random sampling techniques.

If applied appropriately, random sampling is associated with the minimum amount of sampling bias compared to other sampling methods. Research findings resulting from the application of random sampling can be generalized due to representativeness of this sampling technique and a little relevance of bias.Simple random sample advantages include ease of use and accuracy of representation.

It is important to note that application of random sampling method requires a list of all potential respondents (sampling frame) to be available beforehand and this can be costly and time-consuming for large studies.
