How is the ICF different from the Nagi model?

more consideration of the holistic individual, takes into account environmental factors, and gives us more places to intervene


Should a screening tool be highly sensitive or specific? What are you trying to limit?

Sensitive, trying to limit false negatives.


What are type I and type II errors? How do you control for type I error? How are they related?

type I = incorrect rejection of the null hypo (false positive). Controlled with low P value, high CI value. Type II = failure to reject the null (false negative). If you try to control for one type or the other, the risk of the other increases.

when impairments result in a restriction of the ability to perform a physical action, task or activity in a typically expected or competent manner


Nagi model: define disability

What is the difference b/w sensitivity and positive predictive value?

sensitivity: probability that a test will indicate disease when there is a truly as disease. PPV: probability that the person with a positive test will truly have the disease.


ANOVA vs t-test

t-test: compares only 2 groups. ANOVA: compares multiple groups


What is the equivalent of 1 SD on normal bell curve? 2? 3?

1 = 68%. 2 = 95%, 3=99%.

Efficacy = Internal validty, Effectiveness = external validity


What does Kappa measure?



What does chi-square do, and what is a big limitation?
