Design an experiment with one independent variable (with at least two levels) and one dependent variable. Additionally, what levels of measurement would you use when collecting your data?
Example: XYZ hospital wanted to increase compliance of staff using hand sanitizer after every interaction with a patient. In order to gain compliance, they set up a buzzer when staff exited the patient’s room. For the treatment group, a buzzer would ring for 1 second after exiting the room unless staff had pressed the hand sanitizer lever. The control group did not have the buzzer activated, so no sound would emit when exiting the patient’s room.
Independent Variable: Presence of a buzzer sound or not.
Dependent Variable: Number of times the hand sanitizer lever was pressed.
Level of Measurement: Ratio
In your responses to other students, identify a strength or weakness of another student’s example design.
Initial discussion question posts should be a minimum of 200 words and include at least two references cited using APA format. Responses to peers or faculty should be 100-150 words and include one reference. Refer to “HLT-362V Discussion Question Rubric” and “HLT-362V Participation Rubric,” located in Class Resources, to understand the expectations for initial discussion question posts and participation posts, respectively.
