The correlation coefficient, typically denoted as "r," ranges from -1 to +1. A value of +1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation. Generally, values between 0.1 and 0.3 suggest a weak correlation, 0.3 to 0.5 indicate a moderate correlation, and above 0.5 show a strong correlation. The interpretation may vary depending on the context and the specific fields of study.

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.


When two variables are not related the correlation coefficient?

When two variables are not related, the correlation coefficient is close to zero, indicating no linear relationship between them. This suggests that changes in one variable do not predict changes in the other. A correlation coefficient can range from -1 to 1, with values near zero demonstrating weak or no correlation.


Is 0.5 the strongest correlation coefficient?

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


The value of the correlation coefficient is always in the range 0 to 1 true or false?

FALSE: THE RANGE IS -1 to +1


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 range of correlation coefficient and what does its value tell?

The product-moment correlation coefficient or PMCC should have a value between -1 and 1. A positive value shows a positive linear correlation, and a negative value shows a negative linear correlation. At zero, there is no linear correlation, and the correlation becomes stronger as the value moves further from 0.


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.


what is correlation interval?

A correlation interval refers to the range within which the correlation coefficient, a statistical measure of the strength and direction of a relationship between two variables, is assessed. Typically, this interval ranges from -1 to +1, where -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 denotes no correlation. In practice, correlation intervals can also refer to confidence intervals around the correlation coefficient, providing a range of values that likely includes the true correlation in the population.


Can coefficient of correlation be negative?

Yes. The range of r is from -1 to 1. See related link.


What is a correlation coefficient of 0.0731?

This means there is no correlation between the points on a graph. There is no linear relationship between the x and the y values at all. 0.98 is usually deemed to be an acceptable r2 value
