Question 1 • Algebra II

A company wants to learn about the number of its employees who visit the dentist for regular checkups. Which type of study will best help the company discover this information?

Answer
A
survey sample
B
experiment
C
census
D
observational study

Explanation

To find the number among all the company’s employees who get regular dental checkups, the company should collect information from every employee. That is a census. A survey sample would ask only some employees and estimate the total, while an experiment would change something rather than simply gather information.
