D) Not enough information to tell. Question 2 (2 points) Chi-square is distinct from other statistical methods covered in class because... A) ... chi-square requires interval or ratio-level dependent variables whereas the others do not. B)... chi-square is used with only nominal variables whereas the other tests use variables with other levels of measurement C) ... samples used in studies that use the chi-square are not required to be representative of a population. D)... chi-square is a parametric technique whereas the others are not. Question 3 (2 points) One hundred people responded to a survey that asked if level of political involvement (high, medium, low) was related to political affiliation (democrat, republican, independent). What is/are the degrees of freedom for the chi-square statistical test?

Step 1
To calculate the degrees of freedom for a chi-square test, we use the formula: Degrees of Freedom = (number of rows - 1) * (number of columns - 1) In this case, there are 3 rows (political involvement) and 3 columns (political affiliation). Plugging these values Show more…

What can you conclude from the two-way chi-square test that you conducted in Question #4? Fail to reject the null hypothesis; the distribution of political affiliation is the same for all height groups. Reject the null hypothesis; the distribution of political affiliation is not the same for all height groups. Fail to reject the null hypothesis; the distribution of political affiliation is not the same for all height groups. Reject the null hypothesis; the distribution of political affiliation is the same for all height groups. The results of the two-way chi-square test indicate that the frequencies of the political party affiliation options are equal (i.e., equal numbers of Republicans, Democrats, Independents and other), regardless of a person's height. True False

Answer the chi-square questions using the data below. Use α = 0.01? B A 1 2 3 4 1 20 29 11 19 2 9 28 24 21 a) What is the appropriate test statistic? ---Select--- na z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test One-Way ANOVA Within-Subjects ANOVA Two-Way ANOVA Correlation Slope Chi-Square GoF Chi-Square Independence Compute the statistic selected in a): b) Obtain/compute the appropriate values to make a decision about H0. Critical Value = ; Test Statistic = Decision: ---Select--- Reject H0 Fail to reject H0 c) Compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and/or select "na" below. Effect Size = ; Magnitude: ---Select--- na trivial effect small effect medium effect large effect

A chi-square test for independence is performed to test whether political affiliation affects their opinion using 0.01 significance level. Using the above data, the value of the test statistic is 18.148. a) What are your null and alternative hypotheses? b) What are the degrees of freedom of the chi-square distribution of this test? c) What is the p-value? Round to four decimal places. d) What is your conclusion on political affiliation and opinion?
