What is the critical value of correlation coefficient?
± .396 is the CRITICAL CORRELATION COEFFICIENT for a level of significance of 0.05 for a sample of 25. When the correlation coefficient (for a sample of 25 drawn from the same population) is equal to or above .396 (absolute value), there is a 95% chance that the relationship between the variables you observed in your original sample will exist.
How do you determine the level of significance?
To find the significance level, subtract the number shown from one. For example, a value of “.01” means that there is a 99% (1-.01=.99) chance of it being true. In this table, there is probably no difference in purchases of gasoline X by people in the city center and the suburbs,…
