Applications of Degrees of Freedom
Various applications of Degrees of Freedom are discussed below
- Degrees of Freedom in statistic is used to define shape of t-distribution used in t-tests while calculating p-value.
- Different degrees of freedom will display different t-distributions depending on sample size.
- Degrees of Freedom calculations also help us to understand the importance of a chi-square statistic and validity of null hypothesis.
Degrees of freedom also have various applications outside the field of statistics.
For example, take a company that has to decide on how many raw materials to acquire for its manufacturing process. The company has to consider two values within this data set,
- Number of Raw Materials to Acquire
- Total cost of Raw Materials
Company is free to decide on one of the two items, but their choice will affect outcome of other value. When company fixes number of raw materials to acquire, cost of total material is not controlled by the company. Whereas when company decided to limit total amount to spend, company is not able to control quantity of raw material it purchases.
Here the company is only free to choose any one of two values, hence degree of freedom is one in above example.

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.
