10:21 Question Completion Status: The chi-square statistic summarizes... C the probability that the pattern in a cross-tab is due to sampling error the estimated standard error of .how much the observed frequencies in a cross-tab depart from those expected by the null the strength and direction of a bivariate relationship. QUESTIO 2 points Save Answer The chi-square test enables us to assess... ?… the statistical significance of a difference between two samples. the statistical significance of a bivariate relationship in a cross- tab. the strength and direction of a bivariate relationship in a cross- tab. the presence and impact of systematic sampling errors. QUESTIO 2 points Save AnswerExplanation / Answer
The chi sqaure test is a cross tab method to check the observed frequencies with respect to the expected frequencies.
Hence the correct choice is C
as this measures a bivariate relation in a cross tabulation way , hence , choice C
the chi sqaure test is a 2 tail test as the hypothesis is formulated as
H0 : the 2 variables are independent
H1 : the 2 variables are not indepdendent
hence it is not a directional test , so the false statement is choice a
as seen in the chi square table , the table only gives value for a 2 tail test and not for a 1 tail test , hence the correct chocie is a
