Which of the following statements are correct about the phi-coefficient? Check all that apply.It is a measure of correlation between two dichotomous variables.It can be used as a measure of the strength of a relationship between two dichotomous variables.It is a measure of correlation between a dichotomous variable and a continuous variable.It can be used as a measure of the significance of a relationship between two dichotomous variables.Suppose you are looking at the relationship between gender and color preference. You wonder if there is a difference between the preferences ofmales and females for red and yellow. You conduct a quick survey asking different people which color they prefer. The results are shown in the 2 x 2data matrix below:Observed FrequenciesColor PreferenceRedYellowFemale5330Male2047The x2 test statistic for the chi-square test for independence is 17.16. The phi-coefficient isAccording to Cohen's guidelines, the value for the phi-coefficient indicateseffect. Suppose you ask the same question of four times as many people, but the proportions remain the same. The new results are shown in the 2 x 2 datamatrix below:Observed FrequenciesColor PreferenceRedYellowFemale212120Male80188The x2 test statistic for the chi-square test of independence would now be 68.64, and the phi-coefficient would beThus, when we changethe sample size without changing the proportions, thedoes not change, but thedoes.Now, suppose you conduct a slightly different study. Instead of looking at the difference between the preferences of males and females for two colors,you classify your 250 respondents into four categories: male child, female child, male adult, and female adult. You also decide to look at differences inpreferences for five (5) colors: red, yellow, green, blue, and purple. The x² test statistic for the chi-square test of independence is 99.45, andCramer's V would beAccording to Cohen's guidelines, the value for the Cramer's V indicateseffect.
