We have a sample of size 50 from a single population and we are interested to test whether or not the observed frequencies follow a Poisson distribution. In the frequency distribution table, we ended up with 8 classes in this test. What would be the degrees of freedom for this goodness of fit test?

a)6
b)56
c)4
d)5

    The name given to goodness of fit test was derived based on the hypothesis tested and how good the observed frequencies fit a given pattern. To make a goodness of fitness test, the sample size should be large enough so that the expected frequency for each category is at least 5. There are four commonly used goodness of fit tests: The Chi-Square, Kolmogorov-Smirnov, Anderson-Darling, and Shipiro-Wilk. Observed frequencies, denoted by O, are counts made from experimental data - whereby you...
