Is 0.5 the strongest correlation coefficient?

No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).

What are the properties of correlation coefficient?

The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .

What is the correlation coefficient of -2?

A serious error. The maximum magnitude for a correlation coefficient is 1.The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them. Here they are given less than -1 value so it is not a value of correlation coefficient.

Is the Correlation Coefficient of 35 strong?

The correlation coefficient must lie between -1 and +1 and so a correlation coefficient of 35 is a strong indication of a calculation error. If you meant 0.35, then it is a weak correlation.

How is coefficient of determination and coefficient of correlation is related?

Is -0.0001 a correlation coefficient?

Yes it can be a correlation coefficient.

Is 1.5 a correlation coefficient?

No, it cannot be a correlation coefficient.

Is 0.5 the strongest correlation coefficient?

What are the properties of correlation coefficient?

What is the correlation coefficient of -2?

What is the feasible range for r the correlation coefficient?

the correlation coefficient range is -1 to +1

What does a correlation coefficient of zero indicates?

A coefficient of zero means there is no correlation between two variables. A coefficient of -1 indicates strong negative correlation, while +1 suggests strong positive correlation.

What are the properties of correlation?

Is the Correlation Coefficient of 35 strong?
