Answer 1

A random sample is an effective way to select participants because it ensures everyone has the same chance of being part of the study and helps to provide a representative group from the population.

Step-by-step explanation:

A random sample is an effective way to select participants because it ensures that everyone in the population has the same chance of being part of the study. This helps to provide a representative group from the population, increasing the likelihood that the results will accurately reflect the entire population. Random sampling also helps to avoid bias as participants do not know they are part of a study and the researcher has no control over who is in the study.
