Degrees of freedom can be described as the number of independent pieces of information. In estimating the variation around a single mean the degrees of freedom will be (n-1). If we are estimating the variation around a line of a graph, the degrees of freedom would be (n-2) since two parameters have been estimated to position the line.

Degrees of freedom can be described as the number of independent pieces of information. In estimating the variation around a single mean the degrees of freedom will be (n-1). If we are estimating the variation around a line of a graph, the degrees of freedom would be (n-2) since two parameters have been estimated to position the line.
