Question

josé is a student at lake middle school. for a math project, he needs to find out how many pets a typical student at lake middle school has.
a population is an entire group being studied. if the population consists of people, each person is called a member. for josés project, the population is all students at lake middle school.
there are 350 students at lake middle school. why might it be difficult for josé to collect data from all members of the population? choose all that apply.
there might be students who only have cats as pets.
some students at the school might not have any pets.
there would be a lot of data to keep track of.
it would take a long time to survey every student at the school.
it might be hard to contact every student at the school.

Explanation:

• Option 3: With 350 students, there is a large volume of data. Managing and tracking such a large amount of data (e.g., recording the number of pets for each student) is cumbersome.
• Option 4: Surveying each of the 350 students individually would be time - consuming. It requires scheduling, conducting interviews or distributing/collecting questionnaires for every single student.
• Option 5: Contacting every student (e.g., if some students are absent frequently, have no school - provided contact information easily accessible, or are hard - to - reach for other reasons like being in different extracurricular activities at different times) can be a logistical challenge.

Options 1 (students having only cats) and 2 (students having no pets) are about the nature of the data (types of pets or absence of pets) and not about the difficulty of data collection from the entire population.

Answer:

C. There would be a lot of data to keep track of.
D. It would take a long time to survey every student at the school.
E. It might be hard to contact every student at the school.
