Ashanti and Zhi Lu are interested in the differences in coping strategies that individuals who use wheelchairs face when navigating accessibility issues, compared to blind individuals who face accessibility issues. Their independent variable is disability and their dependent variable is navigation of a challenge. They recruit 20 individuals who use wheelchairs and 20 individuals who are blind, and watch them navigate the same accessibility challenge. They control for potentially relevant characteristics, such as participant gender, race, age, and the amount of time they have lived with their disability. Why would their research NOT be considered experimental? They cannot randomly assign individuals to use a wheelchair or be blind. None of the above - this was an experiment. They did not control for potentially relevant characteristics. They did not manipulate their dependent variable.
