A testosterone study reports an average: where did the spread go?
#1
Picture a TEST E300 discussion where someone posts a study's group average, while the linked paper also shows how widely the individual results varied. Everyone in the thread is looking at the same headline number, but the range of results has disappeared from the conversation.

When you read a chart like that, do you go looking for the spread, or does the average tend to become the number you remember? What would you want beside it before making a comparison?

No particular study or outcome is being claimed here. The question is about reading a group summary without treating it as a forecast for one person. A number can be quoted accurately and still leave out the part that would have changed how you understood it.
