And then we would wait some period of time and we would see the average milk production going into the experiment in the no naming group and the naming group. And then we will see, we wait some period of time, six months, a year, and then we will see the average milk production after either not naming or naming the cows for six months. So that's not what occurred here. Here, we just did the survey to everybody and we just asked them this question and we were able to find this connection between whether the cows were named and the actual milk yield. So clearly, not an experiment. This was an observational study. Now, the next thing is what can we conclude here?
