Degrees of Freedom: Explained in simple words

Degrees of freedom refers to the maximum number of logically independent values, which are values that have the freedom to vary, in the data sample.
Degrees of freedom is calculated by subtracting one from the number of items within the data sample.
Degrees of freedom are commonly discussed in relation to various forms of hypothesis testing in statistics, such as a chi-square.
The degrees of freedom in a statistical calculation represent how many values involved in a calculation have the freedom to vary.
To calculate degrees of freedom, subtract the number of relations from the number of observations. For determining the degrees of freedom for a sample mean or average, you need to subtract 01 from the number of observations, n.
