Should we use a chi-square test for homogeneity or a chi-square test for independence in this setting? Justify your answer.
Chi-square test for homogeneity. The data came from a single random sample (n = 4854 young adults aged 19 to 25
vears), with the individuals classified according to two categorical variables (gender and "Where do you live now?").
O Chi-square test for homogeneity. The data came from two independent random samples (n=2488 young adult
females and n = 2366 young adult males aged 19 to 25 years), with the individuals classified according to two
categorical variables (gender and "Where do you live now?").
O Chi-square test for independence. The data came from two independent random samples (n= 2488 young adult
females and n = 2366 young adult males aged 19 to 25 years), with the individuals classified according to two
categorical variables (gender and "Where do you live now?").
O Both tests are appropriate because the data is categorical.
O Chi-square test for independence. The data came from a single random sample (n = 4854 young adults aged 19 to 25
uonra) with the individuals classified according to two categorical variables (gender and "Where do you live now?").
