A sample of 576 men 60 years of age with normal bone density,
osteopenia (a low bone density which may lead to osteoporosis), and
osteoporosis are randomly selected from hospital records and
invited to participate in the study. Each participant's history of
fracture (At least once vs. None) in the past 5 years is obtained
from their medical records. What statistical test is the MOST
appropriate to test whether there is a difference in history of
fracture in the past 3 years between 60-year-old men with normal
bone density, those with osteopenia, and those with
osteoporosis?
a. Chi-square test of independence
b. Chi-square goodness-of-fit test
c. Simple linear regression
d. Three independent-samples t tests
e. (One-way) ANOVA
