Document Summary
Chapter 1: introduction to theory based data analysis. Construct: (cid:373)e(cid:374)tal i(cid:373)age of so(cid:373)ethi(cid:374)g that does(cid:374)"t a(cid:272)tuall(cid:455) e(cid:454)ist i(cid:374) ta(cid:374)gi(cid:271)le for(cid:373) Measured variables: concrete empirical assessments of constructs. Reliability: extent of which a measurement can be reproduced. Validity: which is how well a measure corresponds to the theoretical definition of a construct: measurement error: the deviation between the true value and what was measured. Independent variable: this value is thought to determine the value of other variable. Association: values on the variables tend to coincide with each other. Relationship: one construct influences another construct in a casual matter. Dependant variable: dependant on the independent variable. Parameter: a numerical characteristic of the population. Inferential statistics: the use of probability theory for inferring the properties of a population from a sample. Internal validity: the extent to which conclusion about cause and effect can be drawn from the research. Dichotomous variable: 2 things that are represented as being entirely different.
