Document Summary
Sampling: selecting members of the population to actually collect data from. Random sampling: sampling without a bias to specific members of the population. Assignment: sorting participants into levels (manipulation) of your independent variable. Iv manipulation is suppose to change dv (dependant variable) Confounding variable can change dv (dependant variable) as well. Random assignment: sorting without a bias to specific members of the population. We can minimise the effects of confounding variables by using a within-subjects research design (one participant experiences both control and manipulation) (reduces differences between 2 groups; miminual differences between control and experimental) Within-subjects: joe and still joe (better to eliminate differences between control and experimental groups) Remember that correlation does not always equal causation. A small group represents the population you are interested in. Probability of obtaining the result by chance. P < 0. 05 for statistically significant result (less than 5% that your results occurred by chance)
