Evaluation of watermelons texture using their vibration responses

Fabulous research! Four scientists took 43 watermelons (Crimson sweet), measured their vibration response, rated them using a five-point ripeness scale, built a regression model to predict ripeness from vibration response, checked the model on the same 43 watermelons, got R² = 0.9998, published the results in a peer-reviewed journal.

Debunked in Statistics Done Wrong.
