Alan is conducting a survey to find out the type of art preferred by students in the town's high school. Identify the population of his survey and describe a possible sample of the population.

We know that Alan is conducting a survey to find out the type of art preferred by students in the town's high school.

So, to drive a proper study, he need to take all students in the town's high school as population, because that's the objective.

However, when we drive a statistical study, in most of the cases, we aren't able to apply the study to all the people who represent the population. In that case, we take a population sample, which must represents the total number of students.

The sample is a sub-group of the population, and it must have the same characteristics and qualities as the population, otherwise, the study will be biased.

So, the sample a possible sample must be a certain number of students from each year. First year students, second year students, third year students, and so on. That way the sample will represent the population properly.

The population of Alan's survey is all the students at the town's high school. The sample must be representative of the population. A possible sample would be an equal number of freshman, sophomores, juniors, and seniors.
