Question
A theory can be described as an interdependent set of - - - - - relations between - - - - -
1. proposed, constructs
2. empirical, hypotheses
3. verified, variables
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.
Question 2
A measurement model of attention deficit disorder relates this - - - - - to its - - - - -
1. construct, intervening variables
2. hypothetical variable, observable instances
3. variable, parameters
Answer: The correct option is 2
Reasoning:
Alternative 2 is correct because (a) ‘attention deficit disorder’ is a hypothetical variable
used to refer to a cluster of observable symptoms, and (b) the symptoms are the
observable instances (of behaviour) which are used to measure (e.g. indicate the severity)
of the disorder.
Alternative 1 is incorrect because one requires manifest, not latent variables for
measurement.
Alternative 3 is also incorrect because a model is not a variable, but a theory of the
relationship between ‘referents’ (or hypothetical entities).
Use the following scenario to answer Questions 3 to 5
"Acute stress disorder among patients who suffer from this disorder can be explained in terms of how
the intensity of stress is affected by personality factors, by the nature of the stressors which they
experience, and by the support they experience in their social system. My research will investigate
whether the level of anxiety of these patients can be reduced by providing social support through
group therapy. More specifically, patients receiving group therapy are expected to score lower on the
Manifest Anxiety Scale than patients not receiving therapy"
Question 3
"Acute stress disorder among patients who suffer from this disorder can be explained in terms of
how the intensity of stress is affected by personality factors, by the nature of the stressors which
they experience, and by the support they experience in their social system” is a(n) - - - --

1. hypothesis
2. theory
3. operational definition
Answer: The correct option is 2
Question 4
The dependent variable(s) in my research is/are - - - - -
1. personality factors, nature of stressors, support received
2. whether or not group therapy is received
3. level of anxiety experienced by patients
Answer: The correct option is 3
Reasoning:
In the hypothesis it is indicated the level or intensity of anxiety experienced ‘depends’ on other
variables such as personality factors, the nature of the stressors and support experienced in the
social system, showing that it functions as a dependent or Y-variable which is to be predicted or
explained in the study.
[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).]
Question 5
When interpreting the results of this research I will assume that personality factors and the nature of
the stressors - - - - -
1. do affect level of anxiety, but their effects more or less cancel out over all my patients in the
research sample
2. do not affect level of anxiety
3. do affect level of anxiety, but according to the central limit theorem their average effect will
be zero
Answer: The correct option is 1
Reasoning:
Alternative 1 is correct because it is obvious that the type of stressor may have an effect
on the level of anxiety experienced, but if an unbiased (e.g. random) sample is selected
from the population, the influence of the type of stressor will be averaged over the
sample.
Alternative 2 is incorrect because there are no grounds for assuming that the type of
stressor will not affect anxiety.
Alternative 3 is also incorrect because the central limit theory is not applicable here (it
refers to the nature of the sampling distributions of sampling statistics and not to the
value of specific variables).
