How to understand Degrees of Freedom
We can understand the meaning and concept of the degree of freedom by going through the following example.
Suppose we take four marbles that are to be distributed between four children A, B, C, and D in the same order respectively. Now the degrees of freedom they have is explained as,
- For A we have all four choices of marbles available then the degrees of freedom for A is 4-1 = 3
- For B we have all three choices of marbles available then the degrees of freedom for B is 3-1 = 2
- For C we have all two choices of marbles available then the degrees of freedom for C is 2-1 = 1
- For D we have all only one choice of marbles available then the degrees of freedom for D is 1-1 = 0
Degrees of freedom of the given sample of data is given using the formula,
Df = n – 1
where,
- Df is Degree of Freedom
- n is Number of Choices
How to Determine Degrees of Freedom?
Degrees of Freedom for a set of data is calculated by subtracting one from the number of items within the set. As all items within the set can be randomly selected until there is only one item remaining.

Degrees of Freedom
Degrees of freedom refer to the maximum number of logically independent values, which may vary in a data sample. Degrees of freedom are calculated by subtracting one from the number of items within the data sample.
Degrees of freedom are the maximum number of logically independent values, which may vary in a data sample. Suppose we have two choices of shirt to wear at a party then the degree of freedom is one, now suppose we have to again go to the party and we can not repeat the shirt then the choice of shirt we are left with is One then in this case the degree of freedom is zero as we do not have any choice to choose on the last day.
Let’s understand what are Degrees of Freedom, its formula, applications, and examples in detail below.
