Document Summary
Based on sampling, al gore was the predicted winner. Prediction was rescinded and george bush was predicted winner. Prediction was rescinded and us supreme court overturned a split decision made by the. First half of class dealt with descriptive statistics, second half will deal with inferential statistics. Deals with generalizing beyond the data: generalize from a limited set of observations to a broader set of observations. Using samples to draw conclusions about populations relies heavily on probabilities. We don"t know for sure if our sample reflects the population only say it is probable . Two main sections: general concepts, samples and population, probability, sampling distribution, hypothesis testing, statistical tests we will learn the concepts underlying the test, how to compute, and when to use. Inferential statistics generalize from a limited set of observations to a broader set of observations: population: complete set of observations, sample. Populations and samples must have particular properties to make generalizations.
