| 0:48.5 | wherever you're currently listening. This episode is one that continues on some previous premium exclusive episodes that we've done before, |
| 0:57.1 | where we've taken a concept in nutrition science research and tried to explain that in a hopefully |
| 1:03.9 | useful way that allows you to really understand what this term means, its importance within |
| 1:09.4 | nutrition research, and so that when it comes up |

| 1:46.3 | one was on stable isotopes, what that means, how they're used in nutrition science research, |
| 1:51.3 | and so on. And you'll find a number of them in the premium feed. So today, the concept I wanted |
| 1:58.5 | to discuss is a statistical one that is really useful to understand |
| 2:03.5 | because it can explain some of the results we might see. And so we need to be aware of what that is |
| 2:08.9 | and if someone is making a certain critique that uses this term that we know what they're talking |
| 2:14.8 | about. And then of course, as the title of this episode |
