Unformatted text preview: Outline of topics from Statistics 403 1. Basic definitions [probability, event, sample space, random variable, and and or probabilities]: cumulative probabilities, probabilities of events (11, 12). 2. Expected value [a singlenumber summarizing a distribution, giving a sense of the most representative value]: expectations of functions of random variables (13, 23). 3. Variance [a singlenumber summary of the dispersion or spread of a distribution]: ex plicit calculations (21, 22, 23); standardization (53). 4. Quantiles [the point in the sample space of a quantitative random variable such that with a given probability p , the observed value is less than or equal to the point]: quantiles for sampling distribution of X (61); interquartile range as an alternative to standard deviation (62). 5. Statistical properties of the sample mean [expected value and variance of X for iid data, for data that are independent but not identically distributed, and for dependent data,...
