Used to estimate the extent of the disease in the population

Question 20

Define surveillance study

Answer 20

Is designed to monitor or detect specific disease

Question 21

Define observational studies

Answer 21

investigate association between an exposure and a disease outcome. They rely on natural allocation of individuals to exposed or non exposed groups

Question 22

Define experimental studies

Answer 22

investigates the association between an exposure, often therapeutic treatment, and disease outcome. Individuals are intentionally placed into the treatment groups by the investigators

Answer 25

influences of temporal and seasonal trends on the reliability and accuracy of data

Question 26

4- Describe the observations/data includes what

Answer 26

- descriptive statistical methods provide an exploratory assessment of the data from a study - exploratory data analysis techniques - organization and summarization of data - tables - graphs - summary measures

5- Assess the strength of evidence for/against a hypothesis; evaluate the data. Inferential statistical methods provide a confirmatory data analysis:

Answer 27

- generalize conclusions from data from part of a group to the whole group - assess the strength of the evidence - make comparisons - make predictions - ask more questions; suggest future research
