In the following result: X2(3) = 8.4, p < .05, .05 is degrees of freedom. Hence, Option D is the correct answer.
Degrees of freedom are the maximum number of logically independent, or potentially different, values in the sample of data. One is subtracted from the number of elements in the data sample to determine the degree of freedom.
Subtract the number of relations from the number of observations to calculate degrees of freedom. The number of observations, n, must be subtracted one (1) in order to calculate the degrees of freedom for a sample mean or average.
Degrees of freedom, also known as numerical freedom of variance, is the maximum number of logically independent values that can be present in sample data. Degrees of freedom are frequently brought up while discussing various mathematical hypothesis testing techniques, including the chi-square.
