Snowball sampling - Changing minds

A researcher is studying environmental engineers but can only find five. She asks these engineers if they know any more. They give her several further referrals, who in turn provide additional contacts. In this way, she manages to contact sufficient engineers. Discussion The 'snowball' effect occurs as referrals multiply at each step.

Ball Lab - Bridgestone Tour B RX Ball Review | MyGolfSpy

For example, on a single ball we measured 72, 67.5 and 75. That's a 7.5 compression point range on a single golf ball. We found a 7.5-point delta across multiple balls. The worst ball in the sample had a 9.5 compression point delta across the three points measured." 7.5 vs. 13 would seem to be much worse?
