STAT 2060 Study Guide - Final Guide: Bayes Estimator, Interquartile Range, Standard Deviation
Document Summary
Number of observ. in each interval, ties are assigned to. Monty hall prob: chance you pick the right door, if you switch, chance of winning becomes . vs. statistics (characterize sample x , s, s2) Population (who you apply findings to in real life) vs. Sample (subset of population, random [each has same chance of being picked for study]) Inferential: use info in sample to see says about population. Multivariate: measuring multiple variables, bivariate (2 variables), univariate (1 variable) Observational studies (observe response for specific variable for each individual) vs. Experimental (investigate effects of certain conditions on individ. ) Statistical inference: claim, experiment, likelihood (how likely it is that experimental outcome occurs given that the claim is true), conclusion. Discrete: set of all possible values is finite (counting) Continuous: set of all values is interval (measuring) Frequency distribution: choose range, divide into non- overlapping equal parts (approx. Classes), count upper class, (frequency [ f] = n), relative frequency.
