Data Analytics

Answerable analytical questions

An answerable question names the population, outcome, and comparison of interest.

Rosa's team sends a coupon to online shoppers. Two weeks later, one report calls it a success and another calls it a failure. How could one clearer question have kept the reports from disagreeing?

What you'll learn4 ideas
  • The population is the full group you want an answer about, like first-time online shoppers instead of every customer.
  • The outcome is the measure that matches the result you care about, like the percentage of shoppers who place an order rather than clicks.
  • The comparison is what you judge the outcome against: another group, like shoppers offered the standard price, or a target, like 15%.
  • An answerable question puts the three together: among first-time online shoppers, how does the percentage who order compare between coupon recipients and shoppers offered the standard price?
