 Hello, this is a video about linear regression, finding critical values. You wish to run a test for significant correlation among two variables. You have a data set with 13 subjects, find the critical value for this test. So in this example, all we have to do is find our degrees of freedom, and then we will go to our critical value table and literally just pick out the critical value from there. So my degrees of freedom for this type of test, for a test for correlation, it's always n minus 2, 13 minus 2, which is 11. Degrees of freedom is 11. So go to your critical value table. There's one given to you in the exercise that you're working on, and this is always for a point zero five significant level. You'll never have anything different than that. You go down to your degrees of freedom, and we look at 11. So the critical value when your degrees of freedom are 11 would be 0.553. So once again, degrees of freedom is sample size minus 2, and 11 degrees of freedom give us 0.553. So your critical value is 0.553. So there's an example on how to find a critical value for a linear correlation test. Thanks for watching.
