Mark wants to evaluate a new diabetes monitoring system that uses a phone app that automatically nudges the user to report glucose levels every morning and evening. He recruits participants and then draws a number from a hat to assign them to receive either the new app or the old self-reported paper diary system (to be completed every morning and evening). He compares the two groups on how frequently they record their glucose levels over 6 weeks. Observation, Experiment, or Quasi-experiment? 1. Is there any randomization indicated? If so, what text in the passage above indicates this? 2. Is there any manipulation of the situation indicated? If so, what text in the passage above indicates this? 3. Is there any control/comparison group or situation? If so, as indicated by what text? 4. Based on your answers to 1-3, what type of study design do you think it is? Observation, Experiment, or Quasi-experiment? Explain Please!
