Question

Which of the 4 methods of data collection is involved when a person counts the number of cars passing designated locations on the Los Angeles freeway system? a. experimentation b. observation c. published sources d. surveying

Answer 1

The correct answer is B) observation.

Among the four methods, the method of data collection that is involved when an individual counts the number of vehicles passing designated locations on the Los Angeles freeway system is observation.

When researchers use the method of observation to collect information, this means that a person acts as the observer, he or she is physically in the location to observe the phenomena. In this case, an individual is placed in a specific part of the freeway to observe and count the number of vehicles that cross the designated location.
