N547: Midterm Exam 1 Questions With Complete Solutions
associative hypothesis Correct Answer as one variable changes,
the other changes, no cause is identified
(correlational)
attrition Correct Answer loss of study subjects, decreases rigor
causal hypothesis Correct Answer specifies the direction of the
change in the dependent variable, always directional
(experimental/quasi experimental)
complex hypothesis Correct Answer predicts the relationship
among three or more variables
conceptual definition of variable Correct Answer provides
variable with theoretical meaning, not a method of measurement
concurrent triangulation strategy Correct Answer analyzes both
quant/qualitative data
confounding variables Correct Answer extraneous variables not
controlled for (because found after study started or unable to
control for)
correlational research Correct Answer (quantitative)
examines relationships b/w two or more variables and
determines the type (+/-) and degree of the relationship
, dependent variable Correct Answer outcome, response, or
behavior that the researcher wants to predict or explain and is
measured in the study
descriptive research Correct Answer (quantitative)
explores and describes phenomena in real-life situations
directional hypothesis Correct Answer states nature of
relationship (more, less, increase, decrease)
experimental research Correct Answer examines cause and
effect relationships b/w independent and dependent variables
under highly controlled conditions
grounded theory research Correct Answer (qualitative)
inductive technique where meanings are grounded in the
concrete world as experienced by the participants and
interpreted at a more abstract level
Hawthorne effect Correct Answer individuals can change
behaviors b/c in a study rather than manipulation of independent
variables
highly controlled Correct Answer artificially construed
environments that are developed for the sole purpose of
conducting research
independent variable Correct Answer intervention/stimulus
manipulates or varied by the researcher to cause an effect on the
dependent variable
