Ein Freiheitsgrad, oftmals auch mit df abgekürzt (aus dem Englischen abgeleitet von number of degrees of freedom), gibt die Anzahl frei wählbarer Werte für einen Parameter an. Die Anzahl der Freiheitsgrade steigt mit zunehmender Stichprobengröße und sinkt mit der Anzahl geschätzter Parameter.
One says that there are n − 2 degrees of freedom for error. Notationally, the capital letter Y is used in specifying the model, while lower-case y in the definition of the residuals; that is because the former are hypothesized random variables and the latter are actual data.
Chemists describe the estimated degree of error in a measurement as the uncertainty of the measurement, and they are careful to report all measured values using only significant figures, numbers that describe the value without exaggerating the degree to which it is known to be accurate. Chemists report as significant all numbers known with ...

The margin of error calculates a distance from the survey’s value in which the actual population value is likely to occur. It assesses the precision of a survey’s estimates . A smaller margin of error suggests that the survey’s results will tend to be close to the correct values.
