Research Designs
Experimental Research: researchers manipulate independant variable and observe/measure dependant variable
Correlational Design: scientists passively observe and measure phenomena. No intervention. Identify patterns of relationships.
Validity
Ecological validity: degree to which effect has been obtained under conditions that are typical for what happens in everyday life
External Validity: degree to which finding generalizes from specific sample to larger population
Internal Validity: degree to which cause-effect relationship between variables has been unambiguously established
Studying everyday life
Daily experiences-collect in the momemt self-report data of one's everyday life
Online behaviour- how people act and interact online
Daily behaviour- how our bodies respond to fluctuating demands of our lives
Daily physiology- how our bodies respond to fluctuating demands of our lives
Statistical significance helps quantify whether a result is likely due to chance or to some factor of interest
Random sample: probability based method to select subset of individuals
Cause and effect: concliusions relateed to whether we say our variable is causing changes in the other variable
Generalizability: results of studies with widely representative samples are more likely to generalize to a population
Margin of error: expected amount of random variable in stats
P-Value: tells you how often a random process would give a result at least as extreme as what was found in the actual study- assuming chance was the only factor
