Jason Was Conducting an Evaluation of a Restaurant Waitress

Multiple Choice

Jason was conducting an evaluation of a restaurant waitress. He sat at the table with a list of things to observe in front of him, and the waitress noticed that he was assessing her every move. He noticed that she began acting more professionally around him, was friendlier, and gave him extra attention. Why would Jason have been better off using naturalistic observation for this assessment?

A) So that he could have more experimental control over his independent variable.
B) So that he would be sure to "catch" the waitress behaving unprofessionally.
C) So that he could have been sure to get enough data to use proper statistics.
D) So that his observations would not have changed the waitress's behaviours.
