How is the significance of Pearson's Correlation Coefficient determined?
- By calculating the standard deviation
- By comparing it to the mean
- By comparing to a critical value from the t-distribution
- By squaring the coefficient
The significance of Pearson's Correlation Coefficient is determined by conducting a hypothesis test, which involves comparing the calculated coefficient to a critical value from the t-distribution. If the absolute value of the coefficient is larger than the critical value, we can conclude that the correlation is statistically significant.
