Chapter 12: Q. 63 (page 721)

63. If there are 15 data points in a set of data, what is the number of degree of freedom?

Short Answer

Expert verified

The number of degree of freedom for15data points in a set of data is13.

Step by step solution

01

Given information

There are 15 data points in a set of data, with the number of degree of freedom.

02

Explanation

To experiment with the correlation coefficient, utilize approach pvalues and procedure table of critical values. And to operate the table of critical values only to understand is the degree of freedom. Degree of freedom for a model of sample sizen is:
degree of freedom=n-2.
So, in this point, since the sample size is:

n=15

=15-2

=13

Therefore, the degree of freedom will be 13.
