Primary research methods: lab experiments, field and quasi, questionnaires/ surveys, observation
quasi- closest you can get

Random assignment to condition- you and I have an equal chance of being conditioned
Confounding variable- some outside variable is causing the change
r= correlation index
secondary research methods: narrative reviews/summaries and meta-analysis
Qualitative research- watching and listening, participant observation and ethnographic analysis:

Classic I/O psych field experiments: Greenberg: company was renovating and groups were given
three new offices- one smaller, one the same and one larger. Used to test equity theory (theory of

Ways of measuring: self report/ reports about others, objective/ subjective assessments, obvious/
unobtrusive measures
Data Set: described in terms of -distributions and their shape, measures of central tendency and
measures of variability
Measures of central tendency: mean (average), median (midpoint) and mode (most frequent
Measures of variability: range (ex. how far do you come to see to see a concert) and standard
deviation (don’t have to memorize equation- how different is everyone from the rest)
So you collect some data then you: compare means, calculate correlations

characteristics that we look for when making a decision OR it is an evaluative standard used a way
