Document Summary
Descriptive is when the information is summarised so that it is more easily understood. Inferential is used to draw conclusions about regularities in the data. A variable is something that is able to vary or take different values: e. g. across people gender, height, weight etc. and within people height, weight, job satisfaction etc. Variables are often used within psychology as scores on a particular test, for example. A value is just a number in a category. A score is a particular person"s value for that variable. Categorical or nominal variables values which are not numerical and differ in name only. Numeric or quantitative variables: two kinds of numeric variables: Ordinal or rank-order variables differ in the order in which the variables are placed. Equal interval variables equal intervals between ranks are implied. For example, the difference between a score of 5 and 7 is the same as the difference between a score of 8 and 10 (2).
