Hypothesis
Ans: A prediction about the results
Alternate hypothesis
Ans: Suggests a testable link between variables
One tailed (directional) hypothesis
Ans: Predicts the difference between the groups in your experiment and
predicts which group will do better
Two tailed (non directional) hypothesis
Ans: This predicts a difference but does not say which group will do better
Independent Variable
,2 | Page
Ans: variable that is manipulated
dependent variable
Ans: What is measured (the result of the change)
Operationalised hypothesis
Ans: Defining precisely how you intend to measure the DV and alter the
conditions of the IV
Extreneous Variables
Ans: All other aspects of the experimental setting that may have an
influence on the dependent variable.
environmental / situational factors
Ans: this is anything about the environment (external to participants)
which might affect their performance
, 3 | Page
Lack of standardisation within a procedure
Ans: A way an extraneous variable can occur, if different groups
experience different instructions, are given different stimuli, or if any part of
their experience is different to that of other participants in other groups
this can lead to invalid results.
Participant variables
Ans: these are anything specific to the individual which may affect the
results
Demand characteristics
Ans: this is when participant form an idea about the purpose of the study,
if they think they know what kind of response the researcher is expecting
from them, they might show a response to please the researcher (or do
complete opposite and ruin results)
Researcher bias
