Document Summary
Political science 3n06 semester ii 2014 lecture 1: introduction. We will be exploring two different types of statistics this semester: descriptive statistics. They describe the features of a collection of data: patterns in particular data, different kinds of descriptive statistics. Measures of central tendency; (value that is most typical) They allow us to make inferences about populations. They allow us to explore the probability that what we found to be the case in our sample: is true of the larger population from which the sample was drawn. Allows us to come up with a probability sample, 90% confident etc. Just as there are different types of statistics, there are also different types of variables. Certain statistics should only be used with certain types of variables. These variables have attributes or possible scores that have no mathematical relationship to each other: e. g. Gender, religion, province, political orientation: the categories of the variable can"t be ordered, averaged, etc.
