all that apply:
--
Phi coefficient, ϕ = √(χ²/N) = √ (17.16 / 150) = 0.34
According to Cohen's guidelines, the value for the phi-coefficient indicates strong effect.
--
Phi coefficient, ϕ = √(χ²/N) = √ (51.48 / 450) = 0.34
Thus, when we change the sample size without changing the proportions, the strength of the association does not change, but the significance of the association does.
------
df = (r-1)(c-1) = (4-1)(6-1) = 15
Cramer's V = √(χ²/(N*min(r-1, c-1))) = √( 8.81 /(250*3)) = 0.1084
Cramer's V indicates moderate effect.

Chi-Square Test for Independence Using Chi-Square, we are looking to see if there is a significant difference between what we would expect results to be, and what the actual results were. That is, expected vs. observed. Use alpha = .05 Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data). Response Male Female Total Not at all 23 25 48 Somewhat 13 22 35 Very 26 16 42...

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
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.
You observe 100 randomly selected college students to find out whether they arrive on time or late for their classes. The table below gives a two-way classification for these students.GenderOn TimeLateFemale359Male4313For a chi-square test of independence for this contingency table, what is the number of degrees of freedom?
