Question

Following a group of truck drivers and noting the number of miles traveled for one year refers to which type of statistical study?

Answer 1

Considering that the data is only noted and not changed, this is an example of an observational study.

What are observational and experimental studies?

• Experimental study: In an experimental study, there is an intervention in a sample, and it's effect is studied.

• Observational study: In an observational study, the sample is just analyzed, without any intervention.

In this problem, the data, which is the number of miles traveled, is only analyzed, no interventions are made, hence this is an example of an observational study.
