chapter one (thinking critcally) Flashcards
correlation research
indicated how related one thing is to another
if the two varibles are correlated then knowing the level of either will help us predict the other
does not tell us why
does not imply causation
perfect correlation
occurs when one varibale changes by a fixed amount and another variable chanages by that same fixed amount
scientific method
empiricists (heart of all reasearch)
do this by observing natural behaviours, correlating compoents of behvaiour and doing experiments that reveal cause and effect
hypothesis-observation&testing-data collection-analysis-report
self report
report on your knowledge, beleifs, experiences
interview, surveys, test
limitations; is it honest?
both interview/interviewer can influence
despcriptive research
naturalist observation
watch/observe
descriptive reasearch
case studies
individual/small group research
experiments
method of research that manipulates an indepent variable to measure tis effect on a depdent variable, while controlling the other relevant variable
variable
any characteristic thaat can vary
stress,weight,reaction time, percent correct
operational defination
a statement of produres(operations) used to define research variable
report by others
report by parents, spouses, course evulation
physicological
blood pressure, heart rate, hormonal secretation, electrical brain activity
limitations:interpretive problem
descripitive research
desribe behaviour in natural setting
case study, naturalistic observation, surveys
does not manipulate varible
