Answer 1
Sample size in research is considered to be one of the most important parts to focus on.
From the research of Hooper et al. (2016) it can be argued that in the primary quantitative
research technique, the success of the entire research rests upon the usefulness of the sample size
and its number. Therefore, sample size can be defined as the number of respondents or subjects
on which the research is going to survey and get a sample answer. This sample answer will help
the researcher to create a realistic analysis of the research. Poplawski and Binder (2018)
articulated that a larger sample is always provides enough significance, authenticity and
reliability on the primary data. However, it is also pertinent for the researcher to consider the
time and money for the research. A big sample size always increases the budget of the researcher
and at the same time also extends the time of completion of the research. Therefore, it is very
important for the researchers to consider the sample size as per his budget and time.
There are different variables that can determine the sample size and its efficacy such as
the population size, margin of error, confidence level and the standard of deviation. Population
size is associated with the demography of the total population. For instance, in the current the
total population is 69,000 employees working in 63 Belgian banks. The second part is the margin
of error or the confidence interval. According to Miller et al. (2018) the purpose of assessing the
margin of error is to reduce the faults and biasness in sample size. Therefore, for the current
research, it is important for the researcher to find out the margin of error. The research uses
Cronbach Alpha to check the reliability of the elements and it scored .89. In the research
reliability coefficient of .70 or high is considered to be acceptable. Therefore, the sample size is
acceptable. However, it is important to calculate the sample size with the sample size formula. If

the confidence level is 95% and the .5 standard deviation and a margin of error of +/- 5 % then
the necessary sample size will be 385 approximately. Therefore, for the current research the
sample size is huge and it needs to reduce to a great extent in order to get better results.
Answer 2
The probability random sampling method has been used in this research with the purpose
to choose the respondents irrespective of any criteria on the gender, age or employee level.
As per the research of Etikan, Alkassim and Abubakar (2016) the probability random
sampling practice is highly useful for large sample size. The probability random sampling
method provides equal chance to the entire population and enjoys lesser reliance to the human
judgement. Therefore, it will be effective for the probability random sampling technique to frère
from all sorts of human oriented biasness. There are several advantages and disadvantages of the
probability random sampling techniques. The advantages are as follows,
 The probability random sampling technique is cost effective. There is a random trend of
judgement that makes the probability random sampling choose the samples. Therefore,
no extra costs have been required to choose the respondents.
 The human judgement plays very limited role in the probability random sampling
technique. As a result of that it becomes useful for the probability random sampling
technique to remain free from bias and becomes more effective and accurate (Mara et al.,
2019).
 The probability random sampling technique is a very simple way of choosing the
respondents. Due to its simplicity and less complex and long process the probability
random sampling technique is very helpful for the researchers.
