The simple regression model (SRM) is model for association in the population between an explanatory variable X and response Y. The SRM states that these averages align on a line with intercept β0 and slope β1: µy|x = E(Y|X = x) = β0 + β1x Deviation from the Mean The deviation of observed responses around the conditional means µy|x are called errors (ε). The error’s equation: ε = y - µy|x Errors can be positive or negative‚ depending on whether data lie above (positive) or below the conditional

CheckPoint: TXJ Companies TJX was still using the old Wired Equivalent Privacy (WEP) encryption system‚ which was not hard for the hackers to figure out. One weakness was poorly secured computer kiosks located in many of TJX’s retail stores‚ which let people apply for jobs electronically.

Acceptance sampling is used to determine if a production lot of material meets the governing specifications. Two advantages of sampling are that the cost is lower and data collection is faster than measuring the entire population. Sampling is the process of selecting units (e.g.‚ people‚ organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. Let’s begin by covering some of the key terms in

Types of Sampling In applications: Probability Sampling: Simple Random Sampling‚ Stratified Random Sampling‚ Multi-Stage Sampling * What is each and how is it done? * How do we decide which to use? * How do we analyze the results differently depending on the type of sampling? Non-probability Sampling: Why don’t we use non-probability sampling schemes? Two reasons: * We can’t use the mathematics of probability to analyze the results. * In general‚ we can’t count on a non-probability
