Document Summary
> conversion of abstract constructs into concrete terms. > what is observed & how it is measured. Does it capture what is intended to represent (measurement validity) Does it allow for consistent measurement of the variable being measured across time or separate occasions (measurement reliability) > do the observations hold true outside of the laboratory. > does the studied sample represent the broader population. > where the study takes place may also affect generalizability. > drawing inferences involves evaluating available evidence through logic and reasoning. > karl popper"s view on science is that of falsificationism. Scientific theories take the logical form of if p, then q. Science involves generating ideas & theories which are falsifiable (testable) > disconfirmatory reasoning is used to try and disprove theories. > observations are used to determine whether theoretical predictions are true/false. > modification of the hypothesis and theory as appropriate. > results do not prove anything, they let an idea stand.
