Document Summary
Thursday, november 9, 2017 8:42 am: experiments involve. Observing consequences of that action: well-suited for projects involving limited and well-defined concepts and propositions. Experimental and control groups: independent and dependent variables. Independent - takes the form of a stimulus (present or absent) cause. Dependent - effect, outcome: the classical experiment. Pre-testing: measurement of a dependent variable along subjects. Post-testing: measurement of a dependent variable among subjects after they have been exposed to an independent variable. Experimental group: group of subjects to whom an experimental stimulus is administered. Control group: group of subjects to whom no experimental stimulus is administered and who should resemble the experimental group in all other respects. Hawthorne effect: people being monitored tend to behave differently. Double-blind experiment: experimental design in which neither the subjects nor the experimenters know which is the experimental and which is the control group, selecting subjects. Randomization: technique for assigning experimental subjects to the experimental and control groups https://onedrive. live. com/view. aspx?bsrc=share&bpub=sdx. skydrive&resid=15cdbb404d6f9171!45798&cid=15cdbb404d6f9171&app=onenote&a 1/2.
