how does one define what is meaningful/important change worthy of attention Is a p-value enough...a measure of effect size?

Jochen Wilhelm

excellent answer.

Seyed Mehdi Ahmadi Context is everything. What is the question asked for the data collection? Do the data answer that question with an effect size you can interpret as important in the context? Important means you can reliably predict an outcome in the context.

Jochen is a little optimistic about the direction change interpretation. It should be a possible direction change that requires confirmation.
