(investigation) to collect accurate and reliable data on a topic of

Guru01 - Stuvia
Sample Ans: A subsection or smaller group of research participants
selected from a larger group of research interest.
Population Ans: The entire group of research interest from which a
sample is drawn and to which the researcher will seek to apply
(generalise) the results of their investigation.
Research hypothesis Ans: A testable prediction of the relationship
between two or more variables (events to characteristics).
Experiment Ans: Used to test a cause-effect relationship between
variables under controlled conditions.
Variable Ans: Something that can change (vary) in amount or type and

independent variable (i.e. the treatment).
Guru01 - Stuvia
Control group Ans: The group of participants that is not exposed to the
independent variable.
Extraneous variable Ans: Any variable other than the IV that can cause
a change in the DV and therefore affect the results in a negative way.
Confounding variable Ans: A variable other than the IV that has had an
unwanted effect on the DV, making it impossible to determine which of
the variables has produced a change in the DV.
Order effect Ans: Occurs when performance, as measured by the DV, is
influenced by the specific order in which the experimental tasks are
presented, rather than the IV.
Experimenter effect Ans: Sometimes called experimenter bias or
research bias, it is an unwanted influence(s) on the result which is
produced consciously or unconsciously by a person carrying out
