The population of this study is all first year students in University London who are taking a certain subject. This includes students from all faculties, departments, and programs, as long as they are enrolled in the subject in question. The population size can be determined by the university's enrollment records.
Sample
Since it may not be feasible or practical to study the entire population due to time and resource constraints, a sample of students from the population can be selected for the study. The sample should be representative of the population in terms of relevant characteristics, such as academic background, gender, and ethnicity. The sample size should be large enough to provide statistically significant results, and the sampling method should be designed to minimize bias.
