- when the correlations are >0.80
- when a case control design is utilized
- when the p value is <0.05
- when the predictor occurs before the outcome
5With a chronic condition such as osteoarthritis, you would expect:
- prevalence to be higher than incidence
- incidence to be higher than prevalence
- little to no difference between incidence and prevalence
6Level III studies provide stronger evidence than Level IV studies because they:
- analyze the results of multiple studies
- provide longitudinal data
- are prospective in nature
- use large samples
7A study finds that the number of hours of sleep is positively correlated with GPA. This means that
- more sleep is associated with a higher GPA
- less sleep is associated with a higher GPA
- there is no relationship between sleep and GPA
- more sleep causes you to have a higher GPA
