Document Summary

Hss2381c dr. hogan: intro statistics data analysis. Include numerical facts and figures, involves math, relies on calculations of numbers and how those numbers are interpreted. *statistic research cannot prove anything, it only supports. i. e we can"t prove that smoking causes lung cancer, research shows that it can be one of the causes, but its not 100% of smokers that get lung cancer. Numbers that are used to summarize and describe data (information that has been collected) Does not involve generalizing beyond data at hand; only describe what the data that was collected and can"t generalize to a larger/general population: can speculate but can"t prove it with the data. Us; ask a small number of american to draw inferences for the entire country from the responses received: keep sampling random be sure not to over-represent one kind of person over all the others (sampling bias) I. e survey all florida residents when population is us residents.
