a researcher wishes to test the relationship between age and criminal offending. she gathers a sample and for each person, she collects his or her age (in years) and whether that person has ever committed a crime (yes or no). can she use chi square test? why or why not?
Homework Answers
No, chi square test can't be used in this situation because the primary requirement of using chi square test for independence is that the data should be categorical. Age in years is a ratio scaled quantitative variable and hence, chi - square won't be applicable in this scenario.

hand calculation. please show all works. A researcher classifies a group of people into three age groups and measures whether each person used Facebook during the previous week (yes/no). The researcher uses a chi-square test for independence to determine if there is a significant relationship between the two variables. If the researcher obtains ?2= 6.75, then what is the correct decision for the test? Reject ?? for α = 0.05 but not for α = 0.01. Reject ?? for α...
