The degrees of freedom is a count of the number of variables which are free to vary. This number can be fewer than the number of variables because of constraints imposed by additional information. Suppose, for example, you have n variables and you also know their mean. Knowing the mean is effectively the same as knowing their sum. So (n-1) of the variables can take any value but, after that, the nth variable must be such that all n of them add to the know sum.
Similarly, if you have n variables and are given k means (for k classes), then only n-k of the variables are free to take any value. There are k constraints imposed by the k means.

What are the difference between static degrees of freedom and dynamic degrees of freedom?
Mass and damping are associated with the motion of a dynamic system. Degrees-of-freedom with mass or damping are often called dynamic degrees-of-freedom; degrees-of-freedom with stiffness are called static degrees-of-freedom. It is possible (and often desirable) in models of complex systems to have fewer dynamic degrees-of-freedom than static degrees-of-freedom.
If a related measures experiment and matched subject experiment both produce t statistics with degrees of freedom of 20 which experiment used more subjects?
The matched subject because the experiment involves pairs which halves the df.

How many degrees of freedom does a SCARA robot have?
A scara robot uaually have 4 degrees of freedom
What is the relationship between specific heat and degrees of freedom in a system?
The relationship between specific heat and degrees of freedom in a system is that specific heat is directly proportional to the number of degrees of freedom. This means that as the degrees of freedom increase, the specific heat of the system also increases.
How many degrees of freedom are there at the knee?
The knee has 2 degrees of freedom. Flexion/Extension and varus/valgus rotation.
What does the student's t-distribution refer to in statistics?
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
