SET CORRECT ANSWERS
parametric test for comparing 2 independent groups - CORRECT
ANSWER- independent t-test (unpaired t-test); interval/ratio lvel that is
normally distributed and does not have outliers
nonparametric test for comparing 2 independent groups - CORRECT
ANSWER- Mann-Whitney test; ordinal level data OR interval/ratio that
is not normally distributed and has outliers
parametric comparing 2 dependent groups - CORRECT ANSWER-
dependent/paired t-test; interval/ratio level that is normally distributed
and does not have outliers
nonparametric comparing 2 dependent groups - CORRECT ANSWER-
Wilcoxon signed-rank test; ordinal level data or interval/ratio level that is
not normally distributed and has outliers
parametric comparing 3+ independent groups - CORRECT ANSWER-
one-way ANOVA; interval/ratio level that is normally distributed/no
outliers
nonparametric comparing 3+ independent groups - CORRECT
ANSWER- Kruskal-WAllis ANOVA; ordinal or interval/ratio that isn't
normally distrubted and has outliers
parametric 3+ dependent groups - CORRECT ANSWER- repeated
measures ANOVA; interval/ratio that is normally distributed and no
outliers
nonparametric 3+ dependent - CORRECT ANSWER- Friedman;
ordinal or I/R that is not normally distributed or has outliers
, point estimate - CORRECT ANSWER- best single-valued estimate
for parameter
components of margin of error - CORRECT ANSWER- standard error
of the estimated parameter; a multiplier - a number based on sample
size aka z or t value obtained from statistical tables
Key concepts in the definition of epi - study - CORRECT ANSWER-
systematic surveillance, observation, experimentation all done w/ a
scientific approach
Key concepts in the definition of epi - distribution - CORRECT
ANSWER- the frequency and pattern of health related states and
events
Key concepts in the definition of epi - determinants - CORRECT
ANSWER- the physical, biological, social, cultural, economic, and
behavioral factors that influence health
Key concepts in the definition of epi - health related states or events -
CORRECT ANSWER- all health related events - illness, injury,
disability as well as restore health when disease is present
Key concepts in the definition of epi - specified populations -
CORRECT ANSWER- characteristics of who is healthy, at risk, or who
acquires a disease
Key concepts in the definition of epi - control of health problems -
CORRECT ANSWER- the goal of epi is to identify factor associated
with the development of disease and injury as well as factors to prevent
illness and promote wellness
Descriptive epidemiology - CORRECT ANSWER- the frequency (# of
events) and pattern of health-related states and events ->
who/where/when or person/place/time
