1. Extraneous
Variables
Also called a limitation that can affect
the results or dependent variable other
than the independent variable, also called
the confounding variables.
In this experiment one of the
biggest experimental limitations
would be the participants IQ and
previous experience with problem
solving questions.
2. Dependent
Variables
The variable or thing that is being
measured in the experiment.
The number of problem solving
questions answered correctly
A variable that is present in the
experimental group and not the control
group. The thing that is being changed of
manipulated in the experiment
The group in the experiment that
experiences the independent variable
The group in the experiment that does
not experience the independent variable.
A question or observation that is worthy
of an experimental investigation.
The eating of Breakfast before the
test
7. Hypothesis
A carefully worded, testable, educated
guess that establishes a cause and effect
relationship.
8. Operational
Hypothesis
A more detailed hypothesis where the
variables are fully explained and
‘operationalised’ so we have better ideas
about the experimental method and the
participants involved.
9. Participants
or Sample
The group of people involved in the
experiment and selected from a
population of people
Non-numerical data such as descriptions
of behaviour
Numerical data such as figures and
quantities.
MS psychology students who eat
breakfast will perform better on a
series of problem solving tasks
compared to students who have not
had breakfast.
Ten MS Psychology students (5
boys and 5 girls) who eat a set
breakfast at the same time prior to
school will perform better on a
series of 10 problems solving tasks
compared with a group for 10 (5
boys and 5 girls) Year 10 student’s
who do not have breakfast.

Does eating breakfast increase
your ability to solve problem ?
The behaviour of the students
during the test will be recorded
Experimenters will record the
number of correct responses during
the timed test.
