The chi-square statistic is often used in behavioral data to test for relationships between variables. This procedure is based on the null hypothesis of no association or independence. Which of the following statements is incorrect regarding this analytic technique? It is a nonparametric procedure involving nominal data It examines the difference between the distribution that is observed and the distribution that would be expected, assuming the variables are not related The less the variance between the observed and the expected,...

QUESTION 16 A researcher is using a chi-square test for independence to evaluate the relationship between birth-order position and self-esteem. Each individual is classified as being 1 st born, 2nd bom, or 3rd bom, and self- esteem is categorized as either high or low. For this study, what is the df value for the chi-square statistic? a. 3 b. 1 C. 2 O d. 4
