Why double or blinding in this case is important.
00:05
So in this and how this could cause like a bias in the results.
00:12
So basically to have like a blindness in an experiment, we can have two times.
00:18
We can have the double blind experiment, which is when neither in this case, the person that is like performed, the experiment, so we can say the experimenter here, nor even like the subjects, which are the people they are considered like the patients, know in this case which treatment they received.
00:50
Or for like the subjects don't know and the experimenter, they also don't know, like, which each patient like received.
00:58
So which treatment? so we can put here.
01:03
In this case, it would be like if they were taught like meditation or if they just was, they only said to them that they should relax more.
01:14
So basically when we have a double blindness, we will have this.
01:21
Neither the experimenter or the subjects know their treatment.
01:28
And when we have a single blind experiment, this is basically like one of them will not know.
01:35
Like, could be like one of, in this case, i'm going to say this, like either the experimenter or, in this case, the subject.
01:51
And the one of them don't know.
01:53
Usually it will be the subject.
01:56
But like, it is better to have double blind.
02:00
Because if like i'm going to explain why it's better to have like a double blind experiment.
02:07
So one of them don't know in this case the treatment they receive...
