Assignment 5_Semester_1_2023
QUESTION 1 [15]
“…available survey data on WRA often suffer from not covering the entire economy”
(Lenhardt & Beck, 2016).
This statement relates to which aspect of quantitative data gathering? How would you
apply the characteristics of a good measurement tool to quantitative methods in
researching workplace risk assessments?
(1.1) Quantitative data gathering
Graphical representation
It is often said that a picture speaks a thousand words; this is also true when presenting
your data graphically. Data that is graphically represented is easier for the reader to
understand.
Analysing data ethically
Using statistics ethically means that you are being honest and open. Findings should
be reported honestly and not altered because you or management, for example, do
not like the outcome of your research.
Limitations of study
All studies have some aspects that might be seen as limitations. This does not mean
that the study is not valid, but it is important to mention these limitations to show that
you were aware of and took the limitations into account. It is preferable to be open,
honest and frank about the limitations in your study rather than having the readers
point out the shortcomings.
Assumptions
When doing research, you will have to make certain assumptions. This means
assuming something is true without having concrete evidence to support it.
