How To Find Critical Value Of R Statistics How To Find a Critical Value in R To find a critical value in R you can use the qnorm function for a Z test or the qt function for a T test Here are some examples of how you could use these functions in your critical value
Step 2 Find the critical value of t You can find the critical value of t t in a t table To use the table you need to know three things The degrees of freedom df For Pearson correlation tests the formula is df n 2 To find the Z critical value in R you can use the qnorm function which uses the following syntax qnorm p mean 0 sd 1 lower tail TRUE where p The significance
