QUESTIONS WITH CORRECT
ANSWERS GRADED A+
◍ Population.
Answer: Everyone in a group being studied
◍ Sample.
Answer: a subset of the population (smaller portion) - The S in sample is for
smaller
◍ Representative sample.
Answer: Has the same characteristics as the population as a whole- Random
Sampling would be ideal here
◍ Convenience Sample.
Answer: people who are conveniently available for the study
◍ Archival Research.
Answer: Use of existing records - chat its archives...old newspapers, diaries,
etc.
◍ Longitudinal designs.
Answer: track the development of the same group of participants over time
◍ Cross-sectional designs.
Answer: compare several age groups to each other at same time
◍ attrition.
Answer: downfall to longitudinal studies - the loss of participants over time.
(death, moving, too busy, etc.)
◍ cohort effects.
Answer: one of the downfalls to cross-sectional studies - changes in results
, due to when someone is born, NOT the developmental process.
◍ Sequential designs.
Answer: study of individuals of different ages over an extended period of
time
◍ Correlational Research.
Answer: the study of the naturally occurring relationships among variables
◍ Correlation coefficient.
Answer: number from -1 to +1, indicating the strength and direction of the
relationship between variables, closer to 0 = the weaker the relationship
◍ Negative correlation.
Answer: as one variable increases, the other decreases
◍ Positive correlation.
Answer: A correlation where as one variable increases, the other also
increases, or as one decreases so does the other. Both variables move in the

◍ CORRELATION DOES NOT INDICATE CAUSATION.
Answer: CORRELATION DOES NOT INDICATE CAUSATION
◍ Cofounding variable.
Answer: a factor other than the independent variable that might produce an
effect in an experiment
◍ Illusory correlations.
Answer: the perception of a relationship where none exists
◍ Confirmation bias.
Answer: we accept evidence that fits our beliefs and ignore what doesn't
