Verified step by step guidance

1. Understand the concept of a convenience sample: It is a type of non-probability sampling where participants are selected based on their easy accessibility and proximity to the researcher.
2. Identify the key characteristics of a convenience sample: Participants are chosen because they are readily available and willing to participate, not because they represent the entire population.
3. Compare the options given in the problem: Look for the option that aligns with the definition of a convenience sample.
4. Eliminate options that do not match the definition: For example, a randomly selected sample or a sample that matches the population's demographics are not convenience samples.
5. Select the option that best describes a convenience sample: This would be the option stating that the sample consists of participants who were easily accessible to the researcher or were willing to do the study.
