, 1. 1 Answer: The correct option is 1
Reasoning:
• Alternative 1 is correct because a theory is defined as a “network of
postulated relations between constructs”.
• Alternative 2 is wrong because one does not test relations between
hypotheses, but between variables.
• The relations are postulated (and therefore not verified) so that alternative 3
is also incorrect.
2. 3 Answer: The correct option is 3 Reasoning:
The dependent variable is dependent on the independent variable, or conversely,
the independent variable influences the dependent variable. X affects Y (X is the
independent variable and Y is the dependent variable)
3. 3 Answer: The correct option is 3
Reasoning:
A hypothesis is an educated guess, while a theory is a postulated relation between a
set of constructs.
4. 2 Answer: The correct option is 2 Reasoning:
Operational definitions are used to cross the gap between theory and empirical
research. It does this by describing theoretical constructs in terms of observable
instances, which can be measured and used to test a theory.
5. 1 Answer: The correct option is 1
6. 2 Answer: The correct option is 2 Reasoning:
Intelligence is a latent variable because it cannot be observed directly. The results
of the psychometric test can however be observed directly and can therefore be
regarded as the manifest variable.
7. 2 Answer: The correct option is 2
Reasoning:
• Alternative 2 is correct, because a specific hypothesis is now derived from the
theory presented in the scenario.
• Alternatives 1 and 3 is incorrect because the terms ‘estimated size’ and
‘haziness’ have not been operationally defined in the statement given.
8. 3 Answer: The correct option is 3 Reasoning:
(The dependent variable is usually the one that the researcher is interested in, the
variable that is the focus of the research. The independent variable is something
that the researcher manipulates, to see how this affects the dependent variable (in
other words, the dependent variable is dependent on the independent variable).)
9. 1 Answer: The correct option is 1

11. 3 Answer: The correct option is 3
12. 2 Answer: The correct option is 2
Reasoning:
The independent variable is something that the researcher manipulates, to see how
this affects the dependent variable (in other words, the dependent variable is
dependent on the independent variable).
13. 3 Answer: The correct option is 3
