HELPPPPPPPPPP!!!!!!! Calculate the correlation coefficient for the following data, showing all work. What does it tell you about

stiks02 [169]

Answer:

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

$r=\frac{SSxy}{\sqrt{(SSxx)(SSyy)}}$

To find SSxy

SSxy= ∑ $xy$ - ∑ $\frac{(x)(y)}{n}$

To find SSxx

SSxy= ∑ $x^{2}$ - $($ ∑x $)^{2}$ /n

To find SSyy

SSxy= ∑ $y^{2}$ - $($ ∑y $)^{2}$ /n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.
