Welcome to THE GRAND AVERAGERIAN QUIZ!
The purpose of this quiz is to test our intuitions about the average intervention trial participant.

Question:

There were four co-primary outcomes* in the Let's Move It intervention**. What percentage of the participants are average, in the sense that their baseline measurements fall in the middle 30% range of values on all four outcomes (i.e. median ±15%)?

* if you want to know, they were moderate-to-vigorous physical activity as measured by accelerometry and self-report, minutes spent sitting or lying down, and breaks in sedentary time. But domain knowledge is neither necessary nor sufficient for a good guess!
