Question: What Is A Strong Correlation Coefficient?

Is 0.4 A strong correlation?

Generally, a value of r greater than 0.7 is considered a strong correlation.

Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation..

Is 0.8 A strong correlation?

A coefficient of correlation of +0.8 or -0.8 indicates a strong correlation between the independent variable and the dependent variable. An r of +0.20 or -0.20 indicates a weak correlation between the variables.

Is a correlation coefficient of 0.7 strong?

The correlation coefficient, denoted by r, is a measure of the strength of the straight-line or linear relationship between two variables. … Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship via a firm linear rule.

How do you interpret a correlation coefficient?

High degree: If the coefficient value lies between ± 0.50 and ± 1, then it is said to be a strong correlation. Moderate degree: If the value lies between ± 0.30 and ± 0.49, then it is said to be a medium correlation. Low degree: When the value lies below + . 29, then it is said to be a small correlation.

What does a correlation of 0.25 mean?

Generally yes, a correlation of 0.25 is considered substantial (not necessarily high) depending on what you are looking at. I’ve also seen 0.3 as a cut-off point but we learned that a corr of 0.2 or higher already hints at a low positive correlation.

Is 0.2 A weak correlation?

There is no rule for determining what size of correlation is considered strong, moderate or weak. … For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak.
