So in this question, we're told about bias, and we're asked to find out which of the following is true about bias and research, right? so you know that bias is a term that we use to indicate that the data in a study are being distorted or slanted away from reality by some factor, right? and we're given four things to evaluate here.
00:21
We're supposed to determine if any of these are true about bias.
00:25
So in part a, we're being asked if, well, no, in part a, we have to look at this, right? so part a states that it is the same as manipulation because the researcher determines the treatment to be given.
00:38
Well, we know that this is going to be false, right? we know that bias is something that's often unintended, right? like we don't, if we're being responsible researchers, we aren't going to like, you know, push out a survey or we're expecting to get back biased results because they're going to be useless to us, right? we know that in the case of manipulation, we do this in a controlled environment for the purpose of our study, right? so you might change a variable.
01:06
You might change whether people take like medication a or medication b or placebo.
01:10
We might change that.
01:12
But we know that in this case, manipulation is something we do on purpose for the purpose of our study, whereas by something that is unintended that actually hurts our study.
01:21
So we know that part a is going to be false, okay? part b, the researcher cannot be a source of bias because he or she is in control.
01:33
We know that that's going to be false too, right? we know that obviously in a perfect world we wouldn't want to be a source of bias as the researcher, but we know that it is possible.
01:44
Just like how i mentioned earlier, somebody can choose to, like, you know, maybe intentionally or unintentionally, phrase a question in a way that, you know, makes people lean towards one answer or another.
01:56
So obviously, there's a difference between asking somebody if they like orange juice.
02:03
It's like, obviously okay we'll look at it like this so the first way we can ask is just like you know do you like orange juice and then the second way we could say it is that we could be like well you know considering that producing orange juice has this this and this effect on the environment do you like orange juice right so we'll have like some scary statement and we'll be like do you like orange juice obviously we know that the responses we get in our first question are going to be more realistic than ones we get in our second statement right because chances are when we start off with something that's really scary and intimidating.
02:50
Obviously, we're going to feel, we're going to make our people feel that if they say yes, or, you know, yeah, if they say yes, people are going to judge them a little bit.
02:59
They're going to be like, wow, you support this, this, and this.
03:01
Wow, what a jerk, you know? so we know that sometimes either unintentionally or intentionally, we can sort of be a source of bias in our study, right? it can be something like in the way we we fear of our questions, or it could be another mode of, or it could just be a way that we design our experiment.
03:17
Maybe we design it in a way and we don't realize that it's going to be affecting us in any way.
03:21
But it is definitely possible.
03:22
So part b is false.
03:25
Part c...
