In Statistics and mathematics, the degrees of freedom in a sample are used to correct: A. possible bias between the alternative and null hypotheses.
What is a null hypothesis?
A null hypothesis (
) can be defined as the opposite of an alternate hypothesis (
), and it asserts that two (2) possibilities are the same.
In In Statistics and mathematics, the test statistics of a given sample is calculated with this formula:
Where:
Also, the degrees of freedom in a sample are used to correct a possible bias that exists between the alternative and null hypotheses.
