All right, for this problem, we're supposed to describe how non -responsible lead to a bias.
00:08
And in the study, we had 45 answer to 1 to 5 and 45 answer the 0 to 4 scale.
00:13
So let's just suppose, suppose 45 answer the 1 to 5 scale, but only 43 or 40 of 45 answer.
00:40
The 0 to 4 scale, all right? well, then we'd have two choices.
00:48
Suppose we decide to continue on.
01:08
Suppose we decide to continue with the study and not account for the missing five responses.
01:36
And we make some conclusions, and we're like, well, based on these conclusions, this is what we think.
01:39
The problem with that is that this method assumes that the missing five would have responded similarly to the other 40.
02:18
And yeah, if they did, then we don't really need them to make an accurate assessment, but we don't know that.
02:23
They might have incredibly different views, and those different views could create alliers...
