In this problem, we have been given some statements and we need to determine which of them are false.
00:06
So, first of all, consider the first statement.
00:08
It is said that a scatter diagram can be used to precisely estimate the correlation between variables.
00:15
Now, this is false.
00:18
The reason for that is that the scatter diagram gives a graphical representation of the correlation between the variables, and this gives us a rough estimate of the correlation coefficient.
00:28
It is not possible to use that to precisely estimate the correlation.
00:33
So this is false.
00:35
Next, let us consider the next statement.
00:37
The correlation coefficient ranges between 0 and 1.
00:40
This is also false, and that's because the correlation coefficient ranges between negative 1 and positive 1.
00:47
Next, it is said that when there is a negative correlation between variables, they move in the same direction...
