Nine semesters you will be able to choose which class to take the tenth semester, there will only be one class left to take – there is no choice, if you want to graduate, this is the concept of the degrees of freedom (df) in statistics. For example (degrees of freedom example in real life), if you have to take ten different courses to graduate, and only ten different courses are offered, then you have nine degrees of freedom. In statistics, the degrees of freedom considered as the number of values in a study that is free to vary. In other words, it is the number of independent observations out of a total of ($n$) observations. All this means that the degrees of freedom is a function of both sample size and the number of independent variables. The degrees of freedom (df) or a number of degrees of freedom refers to the number of observations in a sample minus the number of (population) parameters being estimated from the sample data.
