A study suggests that people who have fibromyalgia, so we'll start with that, fibromyalgia, could benefit from yoga sessions.
00:14
So they have a link between the yoga and pain reduction.
00:21
We're looking for possible confounding variables.
00:24
So a confounding variable, or a confound, is a variable where it explains this link.
00:32
So there's not actually a link between yoga and pain reduction, not a causative one.
00:38
But the confounds increases the likelihood of yoga and pain reduction, for example, or decreases the likelihood of both.
00:46
So it's something completely separate from this series of events that explains the link.
00:53
So what could it be? well, immediate example would be that patients who are capable of doing yoga are in turn likely to be a less severe case...
