Dr. Smith is curious about ways to improve worker productivity. She believes that employees with harsher work environments might

actually be more productive, because they are less relaxed and more driven. She gets permission from a sales company to conduct a research study, and she splits the company’s employees into two groups by having people pull a piece of paper out of a hat – each piece of paper has either "bright" or "dim" written on it. The people in the "bright" group have their lighting replaced with harsh, bright light bulbs, and the people in the "dim" group have their lighting replaced with soft, pleasant light bulbs. She then measures their productivity over a 4-week period, and finds that the people in the "harsh" group actually make more sales than the people in the "dim" group.
Which of the following represents the operational dependent variable?

a. worker productivity
b. number of sales made
c. harshness of work environment
d. type of lighting (bright or dim)

Response:

The correct choice is option a (worker productivity).

Rationale:

  • Productivity can be understood as an assessment of how effectively inputs are converted into usable outputs by an individual, factory, manufacturer, or device.
  • In this context, job efficiency acts as the variable being measured. This dependent variable is what the researcher investigates. The researcher assesses job efficiency by modifying independent variables.

Other choices presented do not relate to the example provided. Therefore, the proposed answer is indeed correct.
