Question

Ndahafa Metusalem · Accepted Answer

Final Answer : D, Explanation :  The subjects chosen for an experiment should be carefully chosen so that they are a representative sample of the population. This means that they should be chosen from different geographical areas, socioeconomic classes, and age groups to accurately reflect the diversity of the population. Allowing subjects to choose their own group or limiting them to one specific area or socioeconomic class could introduce bias into the experiment, which could affect the validity of the results.
