How to find critical values for correlation coefficient?
Understand the Problem
The question is asking how to determine the critical values for a correlation coefficient, which is a statistical measure that indicates the extent to which two variables fluctuate together. To answer this, one typically needs to understand the significance level and the corresponding critical values from a statistical distribution, often using a table or calculator.
Answer
Calculate degrees of freedom (v = n - 2) and refer to a critical value table.
To find the critical value for the correlation coefficient, calculate the degrees of freedom (v = n - 2) and refer to a critical value table using this degrees of freedom and your significance level.
Answer for screen readers
To find the critical value for the correlation coefficient, calculate the degrees of freedom (v = n - 2) and refer to a critical value table using this degrees of freedom and your significance level.
More Information
Critical values indicate the threshold above or below which the observed correlation coefficient is deemed statistically significant, at the chosen significance level.
Tips
A common mistake is forgetting to subtract 2 when calculating degrees of freedom: always remember that v = n - 2.
