Document Summary
Inferential statistics: a set of techniques that uses the laws of chance and probability to help researchers make decisions about what their data mean and what inferences they can make from that information. Inferential statistic techniques are a process of logic (a way of thinking through a logical set of steps). The basis of the t-test, f-test, tests of significance of a correlation and beta can be understood using inferential. Inferential statistics is the logical process of using data from a sample, whose characteristics are known, to make inferences about some population, whose characteristics are often unknown. Explained the probability of a person being able to pick out someone with a certain characteristic, such as iq level, from a crowd. Takes a person (for ex. , sarah) to a basketball stadium and asks her to pick out a person with a high. Iq level (after determining the mean iq level, the standard deviation, and the distribution).
