Sorry but how I compare when we compute the degree of freedom by n1+n2-2 and the long structure in the slide

[@luthermaddy1229]

To help, what slide are you referring to? With two samples, the degrees of freedom are computes by adding the number in each sample (n1+n2) and then subtracting the number of samples (-2). For one sample, the degrees of freedom are simply N - 1.

Wow he even used the example in the book.

[@tintin999]

Because the slide is made by the same publication
