An educator wishes to study the effects of sleep deprivation on the ability to concentrate. He decides to study the students in
a calculus class. Before the start of the class, each student is asked about the number of hours slept the previous night. Each student's eye movement is then tracked throughout the lecture. The amount of time is recorded whenever the student is not focused on either the instructor or taking notes. This is an example of: O a randomized experiment. O a sample survey. O a matched pairs study. O an observational study.
In the experiment to determine the effect of sleep deprivation on the ability of the student to concentrate definitely needs an experimental setup rather than a randomized data collection.
<em>Do to the fact that, the experimental used a small sample sized area (Students in a calculus class) to test his hypothesis shows that the setup is a sample survey. </em>
<u>This sample survey result could be extrapolated to the whoe region (the classes in the school or whole school ) to determine if there was a major significance between the two variables.</u>
