He's talking about classifying different stages of a child language development. Okay, so that is purely observational. Okay, because the so observational. Okay, that sense. Oops, this is the researcher. No, not control anything. Okay, so that's one thing you need to remember about. I was the version of that researcher has no oops, this is etcetera has no control. Okay, well what is going on? Oh b yes. We have a new antibiotic being tested ineffectiveness. Okay, By recording how the drug works from patients already taking the drug. This is again observational. Okay, let's do the same thing. It's purely original. Okay, That's the last one. So studying how patients respond when given a placebo as opposed to a little drug. So this is experimental. Yeah, because you can see that the, wow researcher, I was trying to effect changes. So what is going on? So you have comparing a placebo? I was supposed to a little drug. Yeah. So this is actually being administered. Okay, all we can say since no, there is intervention by and that risk at you. Okay. Oops. Okay, I hear the intervention is gonna be the latest drug.
