Answer 1

Descriptive Study

Question 2

Answer 2

• cross-sectional studies

Answer 3

descriptive study

Question 4

This type of study can include case reports & case studies as data sources

Answer 4

Descriptive study

Question 5

This type of study is useful for generating rates of an outcome, identifying populations at risk, or formulating hypotheses about cause of a given outcome

Answer 5

descriptive study

Question 6

this type of study takes a snapshot of a sample population hat includes the outcome of interest and potential risk factors

Answer 6

cross-sectional study

Question 7

this type of study measure both preexisting and new outcomes

Answer 7

cross-sectional study

Question 8

this type of study can only determine prevalence

Answer 8

cross-sectional study

cross-sectional studies cannot assess

Answer 9

cause & effect

Question 10

Answer 10

cross-sectional study

Question 11

Answer 11

case-control studies

Question 12

This type of study although similar to, is faster and cheaper than cohort studies

Answer 12

case-control studies

Question 13

this type of study is suited for studying relatively rare outcomes or those that develop a longtime following exposure

Answer 13

case-control studies

Question 14

This study type assess individuals with and without exposure to a potential risk factor who did not have the outcome of interest at study enrollment

Answer 14

cohort study

Question 15

in this study incidence of the outcome is determined during follow-up observation & compared for the exposed and the unexposed individuals

Answer 15

cohort study

Question 16

Answer 16

cohort study

Question 17

cohort studies are conducted

Answer 17

prospectively

Question 18
