La lettura del giorno è Alertbox, la newsletter quindicinale sull'usabilità di Jacob Nielsen. Oggi ce l'ha coi numeri:
Researchers often perform statistical analysis to determine whether numeric results are "statistically significant." By convention, they deem an outcome significant if there is less than 5% probability that it could have occurred randomly rather than signifying a true phenomenon.
This sounds reasonable, but it implies that one out of twenty "significant" results might be random if researchers rely purely on quantitative methods.[Alertbox]
