Objectives and pitfalls of statistical studies. Structure of data sets, histograms, means, and standard deviations. Correlation and regression. Probability, binomial and normal. Interpretation of estimates, confidence intervals, and significance tests. (Students may receive credit for only one of STAT 220, STAT 221, STAT 311, and ECON 311.) Offered: AWSpS.
This course is a non-mathematical introduction to the basic ideas and methods of statistics. You will learn about the numerical and graphical description of data, correlation and regression, sampling, and inference. The purpose of these statistical methods is to help us give informed answers to important questions. Does the new drug work better than the old one? Do high levels of animal fat in the diet cause certain types of cancer? Does watching too much television cause a decline in children's reading skills? Are state lottery games fair? To answer questions like these, we need more than opinions: we need data and a consistent way of analyzing that data. That is what statistics is all about. I
