The formula to calculate the Degrees of Freedom (DOF) is:
\[ \text{DOF} = \text{N} - 1 \]
Where:
Degrees of freedom is defined as the total number of independent pieces of information that go into any statistical analysis involving sample size.
Let's assume the following values:
Using the formula:
\[ \text{DOF} = 30 - 1 = 29 \]
The Degrees of Freedom (DOF) is 29.
