11. Effect size for the chi-square test for independence Aa Aa Which of the following statements are correct about the phi-coefficient? Check all that apply. It is determined only by the proportions in a 2 x 2 data matrix. It is the same as Cramer's V when the data are a 2 x 2 matrix. It can be used as a measure of the significance of a relationship between two dichotomous variables. * It can be used as a measure...

(1 point) A chi-square independence test is to be conducted to decide whether an association exists between two variables of a populations. One variable has 6 possible values and the other variable has 8. What are the degrees of freedom for the x2-statistic? answer:
Both For the chi Square test of independence, ANOVA, and Regression, there are two variables. Match the data types to the statistical method: Question 9 options: 123 Chi Square Test for Independence 123 Regression 123 ANOVA 1. Categorical – Categorical 2. Categorical – Numerical 3. Numerical – Numerical
The chi-square test for independence is similar to a correlation in that it evaluates the relationship between two variables. True or false. Explain your answer.
The purpose of this activity is to gain experience conducting a chi-square test of independence using technology. Recall the report On the Front Line: The Work of First Responders in a Post-9/11 World. We will use data from this report to investigate the question: Are alcohol-related problems among New York firefighters associated with participation in the 9/11 rescue? Here again are our observed data: No Risk for Alcohol Problems Moderate to Severe Risk for alcohol problems Participated in 911 rescue...
