You are running correlation analysis on a data set with 11 items. You calculate the correlation coefficient to be 0.845.

What is the critical value?

Solutions

Expert Solution

The formula for the test statististic is :-

where r = correlation coefficient

n = sample size

So, , the value of the test statistic.

This , distribution.

let, the level of significance be . Then, if your test is a two sided test ( i.e, ) then, the critical value formula is :

otherwise ( i.e for or ) , the critical value formula is :

Suppose, and the test is a two sided test. Then, critical value :

for one sided test , the critical value is :
