PSYC*2130 Midterm: Research Methods and Ethics
Document Summary
Research methods and ethics: systematic observation (sm) Observe b as it occurs + apply measurement to what"s observed. Naturalistic observation (no: observation that occurs in natural setting. Survey methods on a range of topics: sample representations, wording, correlational study (cs) Correlation: tendency for one variable/event to change as other changes. Study relationships between variables: observe each variable + use statistic tests to find out if or to what degree the variables are correlated. Stronger correlation = better the prediction: range of correlation. Correlations range from 0 to 1, greater from 0 = stronger relationship. Postivive correlation = one variable increases and other increases. Negative correlation = one variable increase but other decrease. Cs don"t indicate direction of relationship: ex. X causes y or y causes x: experimental study (es) Manipulate iv to measure effects on dv: change means there is a causal relationship. Change in one variable produced change in other.
