Solution

In sample distribution, the degree of freedom is calculated as the total number of observations (or data points) minus the number of parameters estimated from the data. In other words, it is the number of values in the final calculation that are free to vary.

Here are the steps to calculate the degree of freedom:

  1. Count the total number of observations in your sample. This is often denoted as 'n'.

  2. Determine the number of parameters estimated from your data. For example, if you are calculating a sample mean, you are estimating one parameter (the mean), so you would subtract one from your total number of observations.

  3. Subtract the number of estimated parameters from the total number of observations. This is your degrees of freedom.

For example, if you have a sample of 10 observations and you are estimating one parameter (like the mean), your degrees of freedom would be 10 - 1 = 9.
