Document Summary
Reading chapter 1, 2 and appendix e. Statistics: science of collecting, displaying, and analyzing data. Data: plural of datum: collection of numbers about a particular topic or set of topics, common mistake: this data , when actually these data . It is important to remember that multiplication and division must be done before addition and subtraction. Response categories for a particular variable are given numeric values. Nominal variables [weakest: discrete, categorical w no implied hierarchy of importance, the least versatile of all levels of measurement. Impossible to measure the distance btwn response categories: gender, visible minority status, eye colour, can"t subtract or get any other data from data, no better or worse just different. Ordinal variables: always discrete, unlike nominal variables, response categories in an ordinal variable can be ranked, but distance btwn categories still cannot be measured, often used w attitudinal scales, marital satisfaction, perceived neighborhood safety.
