The question says, here we are asked about the set of variables which are involved in an experiment.
00:06
So they are asking which of the following factors or variables in an experiment is kept constant intentionally.
00:16
So that we have to point out which is involved in the experiment.
00:21
The first option which is given for us is the confounding variable.
00:26
Okay, so there are many variables involved out of which one of them is confounding variables.
00:32
So what is this confounding variable then? it is a variable which is kept constant or which is kept unaltered intentionally, that is by the will of the performer of the experiment or the researcher.
00:48
So why it is kept intentionally constant because if it is altered or otherwise if it is not kept.
00:56
Kept constant, it alters the value of that of the dependent variable, okay, and also that of the independent variable, okay? so these both are very important for the experiment and this confounding variable changes this factors and this leads to the wrong results in the end of the experiment.
01:23
And second option which is given to us is the continuous variable okay so this is the second option so what is continuous variable then continuous variable is not constant okay it cannot remain constant and it takes the value or range of value okay so between certain set of value this continuous variable can assume any value.
01:53
Say there is a value between 1 to 10 for example so that continuous variable can assume any value between 1 to 10 that is 5 6 7 1 2 anything and coming to the third option the third option is what that is the independent variable so what is this independent variable then so this independent variable is such a variable that is intentionally not kept constant okay so it is very different to that of the confounding variable it is altered to get different results in the experiment and the fourth option is the dependent variable okay so what is this dependent variable then as the name says this dependent variable is dependent on any other variable so which is that variable? it is related to the independent variable...
