Document Summary

Experiment: examines how one variable causes another variable to change, advantages, can establish cause and effect, disadvantages, might not be generalizable to real world situation. Independent and dependent variables: variable: anything that varies in a person or a cross feed. Independent variable (iv) the variable that you manipulate: what the researcher changes to see what happens, dependent variable (dv) the outcome variable that the researcher measures to see if changes in the iv affect it. Get sunlight and reads textbook: control group: the group that isn"t exposed to the ib: this group is used to compare how the iv changes the dv (ex. Don"t get the sunlight & doesn"t read textbook) How psychologists make sense of rssearch results: after collecting data: analyze data using statistics, correlations indicate if there is a relationship between variables. Correlations describe relationships: number ranging between -1 to 1 that indicates how two variables are related to each other.
