Product Case

We are considering adding in a feature where instead of a direct estimate of 5 min, instead displaying a range of say 3-7 min. How would you conduct this experiment? How would you know your results were significant?

  • We are considering adding in a feature where instead of a direct estimate of 5 min, instead displaying a range of say 3-7 min. How would you conduct this experiment? How would you know your results were significant?
  • When shifting from a precise 5-minute estimate to a 3-7 minute range, how would you structure an experimental study to assess user response? How would you establish the statistical significance of the experiment’s outcome?
  • How would you set up a test to evaluate user reception of a new time estimate range (3-7 min) versus a fixed estimate (5 min), and how would you validate the significance of the results?
  • In testing a variable time estimate display (3-7 minutes) against a fixed estimate (5 minutes), how would you plan the experiment? What statistical methods would you employ to confirm the reliability of your results?
  • What experimental design would you employ to compare the effectiveness of a range-based time estimate (3-7 minutes) against a precise estimate (5 minutes), and how would you determine the significance of the results?
  • How would you orchestrate an experiment to measure the impact of providing a time estimate range (3-7 minutes) over a specific estimate (5 minutes)? What criteria would indicate the results are statistically significant?
  • What approach would you take to experiment with replacing a single estimated time of 5 minutes with a range of 3-7 minutes? How would you interpret the data to conclude whether the change is statistically significant?
  • How could you design a test to compare the user experience between a specific time estimate and a time range estimate? What statistical analysis would indicate the results are significant?
  • What methodology would you apply to an experiment aimed at introducing a range estimate instead of a specific time prediction, and how would you evaluate the significance of the experimental results?
  • If we decide to show a range (3-7 minutes) rather than a specific estimate (5 minutes), how would you design the experiment to test this feature? What metrics would you use to determine the significance of your findings?
