A tech company wants to know whether its new software update is user-friendly. It sends a feedback link to all fifty thousand users; five hundred respond, and 90% of those call the update 'excellent.' The company concludes that the update is a success.
This generalization is most likely to suffer from which of the following?
- Non-response bias, in which users with strong opinions are far more likely to respond than the silent majority.
- An insufficient sample, since five hundred is only 1% of the total user base.
- A failure to account for users who lack a reliable internet connection.
- Leading questions that prompted users to give positive feedback.
- An assumption that the update could not possibly have any flaws at all.
