A simple random sample would be less practical for personal interviews because of travel costs (unless the interviews are paid to go to a central interviewing location) is the correct answer.
In this question,
A simple random sample is similar to a random sample. It is a type of probability sampling in which the researcher randomly selects a subset of participants from a population.
In a simple random sample, each object in the population has an equal chance of being chosen and the resulting sample is likely representative of the population. It makes generalization about a population.
Major advantages include its simplicity and lack of bias. The disadvantages are difficulty gaining access to a list of a larger population, time, costs, and that bias can still occur under certain circumstances.
Hence we can conclude that a simple random sample would be less practical for personal interviews because of travel costs (unless the interviews are paid to go to a central interviewing location) is the correct answer.
