Aunty,

"Indicates" is about as good as it gets in scientific parlance. Few things are proven beyond doubt. This is why study results to a tested hypothesis are usually given as: "Reject the null hypothesis" or "Fail to reject the null hypothesis." Accept the null hypothesis isn't on the menu of choices. One logical reason for this is that some day another experiment that is better, or better informed, than today's experiment may come along and reject the hypothesis that was accepted today. Hence, if the data indicate something, then it's a pretty good bet that it's real, but there is always, and I mean always, the nagging possibility that it is wrong.

Sincerely,

Salmo g.
