Every definition I’ve seen of degrees of freedom revolves around the number of items that are free to vary while doing a calculation. But what does that have to do with the probability beneath a t curve. Why should we care and why should the degrees of freedom affect our calculation? Why is there no simple answer? What makes a simple definition so elusive?

Why aren’t degrees of freedom ever defined in a clear manner?
