Population-in statistics to represent the entirety or what you define as your “face” Sample- portion of population Will never get for example, all the women in Tennessee, but can get portion -everything in statistics is based off a portion (so could be an error) A sample can also in theory be any size. (however aswe will learn in the near future, sample size is extremely important and small samples provide results. We have to collect samples of populations because as referenced, it is normally unrealistic or even impossible to obtain data How do we get data? Survey/interviews Collect the same data from multiple people (anywhere from 2-infinity) and identify if there are relationsips between the questions Clinical trials Evaluate/compare a minimum of two groups, control and experimental, evaluate whether the introduction/removal of a specific variable impacts the outcome in the experimental group relative to the control Cohort studies Follow a specific group for an extensive period of time (ex franingham heart study) How accurate is our data? How do we know whether the data we have collected is accurate/ representative? -is it possible for respondents to falsify information?
