Document Summary
Variable = a dimension along which people differ. Must look at least two levels in order to establish a relationship (e. g. , how different levels of self esteem are related to academic performance) Qualitative data: virtually any information that can be captured that is not numerical in nature e. g. , interviews w/ individuals who have read 50 shades; description of drinking. Quantitative data: information is represented by numerical values e. g. , number of pages read; alcohol quantity. Need to define one or more variables to measure. Score: an individual"s value for a particular variable data (plural; datum: singular): . Series of scores, observations, measurements, or facts that can be used for analysis, to reason, or make decisions. Directly observable: straightforward e. g. , weight, height, blood pressure. Inferred states: more complicated if not directly observable e. g. , self-esteem, depression, motivation, anxiety, iq must infer from observable behaviour many options, never 1-to-1.
