Statistics presents a rigorous scientific method for gaining insight into data. - CHAPTER 3 Review of Statistics INTRODUCTION The creation of histograms and probability distributions from empirical data. With so many measurements, simply looking at the data fails to provide an informative account. James B. Do not sell or share my personal information. Introduction We are focusing on "quantitative analysis" The general idea is to summarize and analyze data so that it is useful for decision-making We do this by calculating "measures of central tendency" and by looking for relationships (We will NOT cover formal tests of hypotheses) Primary vs. secondary data sources Data on uses If O(u) is any function of u, the mean value of, Some simple mean values that are useful for, This is a measure of the central value of u, Consider the quantity ?u u - u (deviation from, ? P Values and Confidence Intervals P values provide less information than confidence intervals. Errors Type I error Claiming a difference between two samples when in fact there is none.
