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..
What is a weak correlation?
A weak correlation means that as one variable increases or decreases, there is a lower likelihood of there being a relationship with the second variable.
Is 0.3 A strong correlation?
Correlation coefficient values below 0.3 are considered to be weak; 0.3-0.7 are moderate; >0.7 are strong. You also have to compute the statistical significance of the correlation.
Is 0.2 A strong correlation?
The magnitude of the correlation coefficient indicates the strength of the association. For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association.
Is 0.2 A weak correlation?
The correlation coefficient of 0.2 before excluding outliers is considered as negligible correlation while 0.3 after excluding outliers may be interpreted as weak positive correlation (Table 1).
How do you know if a correlation is significant?
To determine whether the correlation between variables is significant, compare the p-value to your significance level. Usually, a significance level (denoted as α or alpha) of 0.05 works well. An α of 0.05 indicates that the risk of concluding that a correlation exists—when, actually, no correlation exists—is 5%.
