A 2018 study (Lakshmi et al.) studied if the tooth-brushing technique of children was associated with the location of the child (either urban or rural).
A 2018 study (Lakshmi et al.) studied if the tooth-brushing technique of children was associated with the location of the child (either urban or rural).
Two-hundred children were observed brushing their teeth, and their technique allocated to one of five categories.
Whattypeof analysis would be appropriate to determine if the tooth brushing technique was associated with location?
A.A two-samplet-test as we have two samples here: Urban children, and rural children.
B.A test for the mean difference, because children can each use more than one technique.
C.A pairedt-test, because the average brushing technique can be compared for rural and urban children.
D.A chi-squared test, because we would have counts for the number of children using each technique in both rural and urban areas.
E.A test for the regression slope, as the relationship between two variables is being studied.
