Document Summary

Empirical structure- quantum mechanisms- double slit experiment prof. anton zeilinger. Change something just by looking at it- reality is not real. Overcoming issue of external validity: according to metatheoretical structuralist view (not wundt"s structuralism) theories consist of typically several elements, assumptions, relationships. In addition, theories need a description of the paradigmatic method-defines range of intended applications of a theory. Experiment tests whether permission to text decreases feelings of loneliness, independent variables were systematically varied (texting vs no texting) and effect of manipulation is measured with dependent variable (loneliness score) Leads to data obtained under different treatment conditions-data points form distributions. If these distributions are different is the difference meaningful (big enough to attribute it to the treatment, or too small to draw this conclusion?) Statistically significant- if gorup difference in dv is sufficiently bigger than what we would expect. Manipulating iv (treatment) produced a statistically significant effect on the dv (outcome measure)
