module 2 Flashcards
3 descriptive research methods
observational
case study
survey
naturalistic method
observing human/animal behavior in their natural habitats
laboratory observational method
observing human/animal behavior in a controlled situation
case study
in depth study of one or more individuals
survey
questioning individuals on things and describing their response
cons of descriptive methods
do not support reliable predictions
do not support cause and effect explanations
correlational method
assesses the degree of relationship between two variables
the relationship is such that an increase in one variable is typically accompanied by an increase in the other
positive relationship
an increase in one is accompanied by an increase in the other (height up weight up)
negative relationship
an increase in one is accompanied by a decrease in the other (elevation up temperature down)
quasi-experimental
compares naturally occurring groups of individuals; variable of interest cannot be manipulated
(compare alcohol consumption by frats/sororities with other student organizations)
2 predictive/relational methods
correlational
quasi-experimental
participant variable
a characteristic of the subjects that cannot be changed
sample
group of people who participate in study
population
all the people about whom the study is meant to generalize
random sample
a sample achieved through random selection in which each member of the population is equally likely to be chosen
