Calculate the degrees of freedom for a data set.
A table represents the possibility of an association between eye color and hair color
What is the degrees of freodom?
Homework Answers
degrees of freedom is 1
because in case of chi square goodness of fit test degrees of freedom is n -1
where n is number of categories.
in given table n is 2
hence degrees of freedom is 2 -1
so degrees of freedom is 1
