Question 1:
Reliable instruments are not prone to fluctuations and are stable in measuring.
Although perfect reliability is impossible to achieve, some procedures can be followed
to increase the reliability of measures.
Which procedure can be used to increase the precision of measurement of an
instrument?
a) Ensure the clarity of the items and only measure what is necessary.
b) Minimize the effects of external events and remove distractions or noise from the
room.
c) Ensure that all participants should receive the same information prior to or during
the completion of the questionnaire.
d) Develop a draft version of the measure or using a subsection to test before
implementing the study will enable timely changes to increase reliability.
e) Use two or more indicators (e.g. two or more questions in a questionnaire) to
measure each attribute of a variable.
Rationale
“Although perfect reliability is impossible to achieve, some procedures can be followed
to increase the reliability of measures:
Increase the precision of measurement: Ensure the clarity of the items and only
measure what is necessary. “ ( Fouche et al., 2021, pp. 468).
A researcher would like to perform a t-test. However, the sample in comparison groups
is too small and the distribution of the scores of the dependent variable shows a serious
deviation from normality.
Which test would be appropriate in this case?
a) T-test for dependent groups
b) Non-parametric tests
c) One-way ANOVA test
d) T-test for independent groups
