00:01
So, a correlation of minus 0 .75 indicates a strong negative correlation.
00:13
Here is the interpretation.
00:26
So, this indicates a strong negative correlation.
00:34
So, the interpretation can be broken down into the four parts.
00:38
The first one is strength.
00:40
So, the strength here, the correlation coefficient is minus 0 .75.
00:47
So, it is relatively close to minus 1 .0.
00:52
So, in general, the closer the correlation coefficient is to minus 1 or 1, the stronger the correlation.
01:04
In this case, it is considered a strong correlation because it is close to minus 1.
01:10
Now, the second aspect is the negative or positive.
01:20
What does it say? so, the negative sign indicates a negative correlation.
01:34
And similarly, a positive sign indicates a positive correlation.
01:39
In this context, as alcohol use increases, the test scores tend to decrease.
01:44
So, they both appear in opposite directions.
01:49
So, as alcohol increases, test scores decrease...
