background image 9/19/2016 Exam 2 | Evernote Web 8/10 Upper 95 % CI + Prevalence +(1.96 √(prevalence*1­prevalence)/ (sample size)
Lower 95 % CI ­  Prevalence +(1.96 √(prevalence*1­prevalence)/ (sample size)
***CI measures precision of the sample, how close are the results from the sample from the population? Strengths of Cross sectional Inexpensive
Can study several exposures or outcomes at once
Short duration
 Establish a foundation for additional/future hypotheses and analytic studies
Weaknesses of Cross sectional Cannot establish cause and effect
Cannot establish temporality. In other words, we cannot
determine if exposure occurred before outcome?  Those who respond or participate are probably different than those who do not *****Serial Survey: Cross­sectional survey that is conducted over a period of time Correlational / Ecologic Studies (exposures and outcomes) of  groups 
measurement: correlation coefficient (linear relationship)
Ecologic Fallacy­ false impression that observed conclusions for the group hold true
for the individual
Case Studies Summary of an individual’s health, information/experience (good for something new)
Including: Demographics, Spatial, Social, Symptoms, and Exposures
