What is a good correlation value?

In general, for the coefficients Pearson's r and Spearman's ρ, values from 0 to 0.3 (or 0 to -0.3) are biologically negligible; those from 0.31 to 0.5 (or -0.31 to -0.5) are weak; from 0.51 to 0.7 (or -0.51 and -0.7) are moderate; from 0.71 to 0.9 (or -0.71 to 0.9) are strong correlations; and correlations > 0.9 (or < ...

Is 0.4 a strong correlation?

A correlation of 0.4 indicates a moderate positive correlation. For example, a researcher might find that students' SAT scores and GPA have a moderate positive correlation. This means that a student's GPA can be used as a moderate indicator of that student's SAT score and vice versa.

Is 0.29 a strong correlation?

General guidelines for evaluating the strength of the relationship are as follows: A correlation coefficient of 0.1 to 0.29 (or −0.1 to −0.29) indicates a weak correlation. A correlation coefficient of 0.3 to 0.49 (or −0.3 to −0.49) indicates a medium correlation.

Is 0.75 a high correlation?

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).

Introduction to Correlation (Statistics)

Is .30 a weak correlation?

A correlation coefficient of . 10 is thought to represent a weak or small association; a correlation coefficient of . 30 is considered a moderate correlation; and a correlation coefficient of . 50 or larger is thought to represent a strong or large correlation.

What is the rule of thumb for correlation?

63) introduces the following rule of thumb to help students decide if the observed value of the correlation coefficient is significant: Rule of Thumb No. 1: If |rxy| ≥ 2/ √ n, then a linear relationship exists. This paper provides statistical justification for the rule's use.

What correlation is too low?

If we wish to label the strength of the association, for absolute values of r, 0-0.19 is regarded as very weak, 0.2-0.39 as weak, 0.40-0.59 as moderate, 0.6-0.79 as strong and 0.8-1 as very strong correlation, but these are rather arbitrary limits, and the context of the results should be considered.

Is 0.3 a low correlation?

For example, a correlation coefficient of 0.2 is considered to be negligible correlation while a correlation coefficient of 0.3 is considered as low positive correlation (Table 1), so it would be important to use the most appropriate one.

How to tell if a correlation 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.

Is 0.28 a weak correlation?

Values between 0 and 0.3 (0 and -0.3) indicate a weak positive (negative) linear relationship via a shaky linear rule. Values between 0.3 and 0.7 (-0.3 and -0.7) indicate a moderate positive (negative) linear relationship via a fuzzy-firm linear rule.

Is 0.29 a weak correlation?

It's important to note that the strength of the relationship is determined by the absolute value of the correlation coefficient. So even though 0.29 is positive, it is still considered weak because its absolute value is not close to 1.

How to interpret correlations?

The direction of the relationship (positive or negative) is indicated by the sign of the coefficient. A positive correlation implies that increases in the value of one score tend to be accompanied by increases in the other. A negative correlation implies that increases in one are accompanied by decreases in the other.

What is considered poor correlation?

While there is no clear definition of what makes a strong correlation, a coefficient above 0.75 (or below -0.75) is considered a high degree of correlation, while one between -0.3 and 0.3 is a sign of weak or no correlation.

Is 0.1 a good correlation?

Positive correlation is measured on a 0.1 to 1.0 scale. Weak positive correlation would be in the range of 0.1 to 0.3, moderate positive correlation from 0.3 to 0.5, and strong positive correlation from 0.5 to 1.0. The stronger the positive correlation, the more likely the stocks are to move in the same direction.

What is a bad correlation?

A positive correlation indicates two variables that tend to move in the same direction. A negative correlation indicates two variables that tend to move in opposite directions. A correlation coefficient of -0.8 or lower indicates a strong negative relationship. A coefficient of -0.3 or lower indicates a very weak one.

What is the weakest possible correlation?

Possible values of the correlation coefficient range from -1 to +1, with -1 indicating a perfectly linear negative, i.e., inverse, correlation (sloping downward) and +1 indicating a perfectly linear positive correlation (sloping upward). A correlation coefficient close to 0 suggests little, if any, correlation.

Is 0.2 a good correlation?

Correlation gives us information on the strength and the direction of a relationship between two or more variables. It can range from -1 to +1. A correlation of 0.2-0.39 is considered weak, 0.40-0.59 as moderate, 0.6-0.79 as strong and 0.8-1 as a very strong correlation.

What is an acceptable correlation?

While most researchers would probably agree that a coefficient of <0.1 indicates a negligible and >0.9 a very strong relationship, values in-between are disputable. For example, a correlation coefficient of 0.65 could either be interpreted as a “good” or “moderate” correlation, depending on the applied rule of thumb.
