Quizplus · Accepted Answer

A representative sample is one that accurately reflects the characteristics of the population being studied. In this case, the percentages of males and females and young and old individuals in the sample match those in the total population, indicating that it is representative. A convenience sample is one that is easily accessible or convenient for the researcher, and may not be representative of the total population. A cross-cultural sample involves individuals from different cultural backgrounds and may not pertain to this scenario. A random sample involves selecting individuals randomly without any specific characteristics in mind, which is not the case here since the percentages of males and females and young and old individuals are already determined.
