To determine what is true of a random sample, we need to understand the concept and purpose of a random sample. A random sample is a subset of a population that is selected in such a way that each member of the population has an equal chance of being chosen. Therefore, the correct answer is option D) Each member of the population has an equal chance of being selected.
To determine this, one approach is to eliminate options that are incorrect.
Option A) It is not the only way to sample a population. While a random sample is one method of sampling a population, there are other sampling techniques available, such as stratified sampling or convenience sampling.
Option B) Each member of the sample being a volunteer is not a characteristic of a random sample. A random sample aims to include members of a population without any judgment or personal choice, so volunteering is not a prerequisite.
Option C) Random sampling is not always the easiest way to sample a population. Depending on the circumstances, there may be other sampling methods that are more suitable or practical. The ease of sampling varies depending on the specific context and the goals of the study.
Thus, after eliminating the incorrect options, we are left with option D) Each member of the population has an equal chance of being selected, which is true of a random sample.
