what is degree of freedom

1- Degrees of freedom represent the number of ways in which the observed outcome categories are free to vary.

2- Degree of freedom refers to the minimum number of logically independent values, which are values that have the freedom to vary in the data sample.

3.Degrees of freedom represent the number of ways in which the observed outcome categories are restrict to vary.
