danjs · Answer

had to look up correlation coefficient... here is where i went http://statistics.about.com/od/Descriptive-Statistics/a/How-To-Calculate-The-Correlation-Coefficient.htm

danjs · Answer

that is pretty close to 1.   The data will fall very close to a straight line.

danjs · Answer

The relationship between x and y will be the slope of the line

a?

danjs · Answer

What defines "strong" and "weak" relationships?

perl · Answer

if correlation coefficient is near 1, there is strong positive (linear) relationship

ttp · Answer

so a right?

perl · Answer

'strong' is kind of vague, but you can make it more precise using statistical tools (hypothesis testing , confidence levels) this is a good resource https://onlinecourses.science.psu.edu/stat501/node/250
