Now here in this question, you are giving a number of multiple choice questions.
00:03
So we are going to look at them one by one.
00:05
The first question is really about educated guess, right? in science, well, in science, educated guess basically is called hypothesis, right? the correct answer is this.
00:19
And the second one, manipulate the variable, is also known as the dependent variable, right? and which one is done to test the hypothesis of course, experiments, right? experiments are done to test hypothesis.
00:38
Anything can change in experiments called a variable, right? a variable does not change, it's called a variable that does not change.
00:51
It's called a controlled variable, right? it is defined as putting something into use or operation based from the outcome of experiment and obviously is as putting something into use.
01:09
Or operation based on the outcome of experiment, of course, is a notification, right? when you decide whether or not the data supports arranging hypothesis, when you draw a conclusion, right? what do you call a theory of logical step? that's a lot in order not to solve a problem...
