A chi-square independence test is to be conducted to decide whether an association between two variables of a populations.
Given one variable has r=6 possible values and another variable has k=8 possible values.
Therefore, degrees of freedom for chi-square statistic is:
df=(r-1)*(k-1)
=(6-1)*(8-1)
=5*7
=35
df=35

A chi-square significance test is performed to examine the association between two categorical variables in a 6 x 6 table. What are the degrees of freedom associated with the test statistic? df= 5
When we carry out a chi-square test of independence, the chi-square statistic is based on (rxc)-1 degrees of freedom, where r and c denote, respectively, the number of rows and columns in the contingency table. True or false
Perform a chi-square independence test using the critical value approach, provided the conditions for using the test are met. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the critical value, to compute the value of the test statistic, and to state your conclusion. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the question correctly. The sample results...
