Justification: In this study the results would be biased because all the parts of the population are not included in the study and also some of them might be favoured. Since the sample does not include all the parts of the population, the range would be restricting to determine the association between the variables of strong academic performance and high school GPA and average amount of time spent studying per day because population cannot be good representative of the population.
