Question

Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a plane)? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in feet per minute) of each. What type of study design is being performed?

Answer 1

Observational study

Step-by-step explanation:

An observational study is one in which the researcher draws inferences from a sample to a population, but where the independent variable is not under the control of the researcher. This can occur for various reasons, but most often, it is the result of logistics or ethical concerns. In this example, the researcher cannot manipulate the way people operate. He cannot divide them into groups nor can he have a control group. However, he can overcome these problems in logistics by simply observing their behaviour.

Answer 2

The answer is: a comparative study.

Step-by-step explanation:

A random sample of two populations is being studyied, the population of those who are departing and the population of those who are arriving; in this sense the research methodology is a comparative study that intends to compare the same variable among both populations. The comparison of both will answer the research question.
