Answer 1

C. Open ended questions

Open ended questions cannot be answered in a simple yes or no. The require wider discussion and elaboration. Hence the responses require enough data or information in order to be categorized and coded.

D.  Identify sampling frame from research objectives

Identifying the sampling frame is the first step in the probability sampling process. For example, if a company has 500 employees, then accordingly the sample frame will be 500.

A. Response categories do not overlap

Mutually exclusive response ensures that each individual answer is different from one another. Survey writers need to double-check their responses to ensure that such a scenario is avoided.

A. Random Sampling

Random sampling allows researchers to perform analysis with a lower margin of error. This is because the whole process is randomized, and the random sample is a clear reflection of the general or entire population which provides an accurate insight.
