Same race effect...........
If you got a 680 SAT score, you're probably wondering how you compare to other students, and whether a 680 is good enough to get into college.
The truth is, it depends on your personal college goals and where you want to apply.
Note: this 680 score guide is for the New SAT, out of 1600. This score corresponds to a 870 in the old SAT out of 2400.
The given statement about the correlation between two variables is; False
<h3>Pearson's correlation coefficient </h3>
Pearson's correlation coefficient is the measure of linear correlation between two sets of data.
Pearson's r is always between the values of -1 and +1.
In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.
Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.
Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.
