The time required to cure concrete is pivotal in the construction business.Insufficient curing time results in lower structural strength, which can create hazardous conditions.Conversely, too much curing time wastes valuable resources and may result in greatly inflated building costs.To help ascertain the minimum curing time, a random sample of 80 poured concrete foundations is drawn.The total time to completely cure each foundation is recorded.This study is best described as a(n) _________________ study.
A) observational
B) longitudinal
C) experimental
D) inferential

Question

Quizplus · Accepted Answer

This study is observational as the researchers are simply observing and measuring the time required to cure concrete in a sample of foundations. They are not manipulating any variables or imposing any treatments, which would be necessary for an experimental study. This study is also not longitudinal because it is only measuring one point in time for each foundation. Finally, it is not inferential because it is not making any predictions or inferences about a larger population beyond the sample observed.
