Smallest Worthwhile Change - what is the 0.2?

Postby joclubbsportsci » Sat May 14, 2016 5:12 pm

In our journal club thread we have posted Martin Buchheit's new editorial 'Chasing the 0.2' viewtopic.php?f=10&t=4

But what is the '0.2'? When using magnitude based inferences to statistically analyse data, an effect size of 0.2 (one fifth of the between-athlete standard deviation) represents the 'smallest worthwhile change' in team sports.

For more on this, Will Hopkins's website http://www.sportsci.org and specifically the following article are must reads:

How many people try to incorporate the SWC into their data in the applied setting? How do you find it? How do you go about explaining this concept to the coaches, athletes and colleagues you work with?
