A correlation greater than 0.8 is generally described as strong, whereas a correlation less than 0.5 is generally described as weak. These values can vary based upon the “type” of data being examined. A study utilizing ‘core’ scientific data may require a stronger correlation than a study using social science data.

What is a good Pearson correlation value?
The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement. A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation.
Is 0.24 A strong correlation?
Although there are no firm cutoffs for strength, let us say that absolute correlations |r| greater than or equal to 0.7 are ” strong.” Absolute correlations less than 0.3 are “weak.” Absolute correlations between 0.3 and 0.7 are moderate.
Is.40 a strong correlation?
40, which is certainly larger than the. 08 from the U.S. study, but it’s far from the near-perfect correlation conventional wisdom and warning labels would imply.
What is a good correlation coefficient?
The possible range of values for the correlation coefficient is -1.0 to 1.0. In other words, the values cannot exceed 1.0 or be less than -1.0. A correlation of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.
What does Pearson’s r tell us?
Pearson’s correlation coefficient is the test statistics that measures the statistical relationship, or association, between two continuous variables. It gives information about the magnitude of the association, or correlation, as well as the direction of the relationship.
Is 0.2 A strong 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.
What does a correlation of 0.75 mean?
r values ranging from 0.50 to 0.75 or -0.50 to -0.75 indicate moderate to good correlation, and r values from 0.75 to 1 or from -0.75 to -1 point to very good to excellent correlation between the variables (1).
What does an r2 value of 0.9 mean?
Essentially, an R-Squared value of 0.9 would indicate that 90% of the variance of the dependent variable being studied is explained by the variance of the independent variable.
What does an R value of 0.25 mean?
And an R-Squared of 0.25, which means that 25% of the variance in creativity scores has been accounted for, is quite respectable – except that there may be a couple of issues with your methodology.
What is a strong or weak correlation?
The Correlation Coefficient When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation of -0.97 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.
What does a correlation of.50 mean?
A correlation coefficient of r=. 50 indicates a stronger degree of linear relationship than one of r=. 40. Likewise a correlation coefficient of r=-. 50 shows a greater degree of relationship than one of r=.
Is a correlation of.5 strong?
Correlation coefficients whose magnitude are between 0.7 and 0.9 indicate variables which can be considered highly correlated. Correlation coefficients whose magnitude are between 0.5 and 0.7 indicate variables which can be considered moderately correlated.
How do you interpret an R?
The Pearson correlation coefficient or as it denoted by r is a measure of any linear trend between two variables. The value of r ranges between −1 and 1. When r = zero, it means that there is no linear association between the variables.
How do you know if a correlation coefficient is significant?
Compare r to the appropriate critical value in the table. If r is not between the positive and negative critical values, then the correlation coefficient is significant. If r is significant, then you may want to use the line for prediction. Suppose you computed r=0.801 using n=10 data points.
What is the formula of Karl Pearson’s coefficient of correlation?
The Pearson correlation coefficient is symmetric: corr(X,Y) = corr(Y,X). A key mathematical property of the Pearson correlation coefficient is that it is invariant under separate changes in location and scale in the two variables.
