Question

What is Cramer's V for each of the following values for the chi-square test for independence? (Round your answers to two decimal places.) (a) x^2 = 3.11, n = 60, df_ = 1 V = (b) x^2 = 7.96, n = 110, df_ = 2 V = (c) x^2 = 11.75, n = 150, df_ = 3 V = Altamura, DelI'Osso, Vismara, and Mundo (2008) measured the relationship between gender and duration of untreated illness (DUI) among a sample of those suffering from major depressive disorder (MDD). The following table lists the observed frequencies from this study. Compute a chi-square test for independence at a 0.05 level of significance. () X^2_ = Decide whether to retain or reject the null hypothesis. Retain the null hypothesis. Reject the null hypothesis.

Explanation / Answer

Cramers V=sqrt(chi2/n*df)

a)sqrt(3.11/60)=0.227

b)sqrt(7.96/110*2)=0.190

c)sqrt(11.75/150*3)=0.161

b)Using the chi square calculator plugging the values we get chi square value of 2.6714. p value=.102169

By p value result is not significant i.e null hypothesis is true.
