Research Methods
Code: _________________________
- A testable prediction, often implied by a theory. _______________________
- A technique used to sample a population that pretty much guarantees the
sample will be representative of the population. This is because each
subject has an equal chance of being selected for the survey. ____________
____________
- The difference between the highest and lowest scores in a distribution.
_____________
- The most frequently occurring score in a distribution. ___________________
- A research method in which an investigator manipulates one or more factors
(independent variables) to observe the effect on some behavior or mental
process (the dependent variable). _____________________________
- Observing and recording behavior in naturally occurring situations without
trying to manipulate and/or control the situation. _________________
_______________
- A statement of the procedures used to define variables in research. This
tells us exactly how variables are measured. __________________
_______________
- The tendency to believe, AFTER learning the outcome, that you "knew
it all along". _________________ ________________.
- The repetition of an earlier research study (usually with other subjects
and under a different situation) in order to see whether the basic findings
generalize to other participants and other circumstances.
___________________________
- The perception (or belief) that a relationship exists between two
variables where none actually exists. ___________________
___________________
- A technique in which a single individual is studied in depth.
_____________ __________
- A statistic that measures how strongly (and in what way) two variables are
related. It also allows us to predict the value of one variable from
knowledge of the other variable. _____________________
______________________
- The condition (or group) in which subjects in an experiment are exposed to
the "treatment". In other words: This is the condition in which
subjects are exposed to the version of the independent variable that is
believed to have an effect on the dependent variable. ______________________
______________________
- An experimental procedure in which both the research participants and the
research staff are unaware of who is in the experimental group or the
control groups. _____________________ ______________ procedure
- The behavior or mental process that is being measured. This variable may
change in response to the manipulation(s) of the independent variable.
______________ _________________.
- The average of a distribution of scores, obtained by adding the scores and
then dividing by the number of scores. _____________________
- An inert substance (usually a sugar pill) used in place of a real drug in
order to determine if the real drug actual has an effect beyond
"wishful thinking" or the "self-fulfilling prophecy.
________________
- The middle score in a distribution. Half of the scores are above it and
half are below it. ______________________
- A score that tells us how much an individual score varies around the mean
of a distribution of scores. _________________ __________________
- A technique used to assess the attitudes and/or behaviors of a group of
people. This is usually accomplished by administering questionnaires to a
randomly selected sample of subjects. ____________________________
- Assigning subjects to the experimental and control conditions by random.
The helps to reduce pre-existing differences the two groups.
__________________ ____________________
- The experimental factor that is manipulated by the experimenter. This
factor is believed to have an effect on one (or more) other variables.
_______________ ________________
- The condition (or group) in an experiment that contrasts with the
experimental condition and serves as a comparison for evaluating the true
effect of the treatment (independent variable). ____________________
