DATA COLLECTION METHOD

Questionnaire surveys were chosen after considering other research techniques because it is common method to collect primary data, however, the question must be simple, self-explanatory, clearly structured and easy to understand since we will not be with them to explain the questions. Other reasons for choosing as follow:
i. Primary data need to be collected from a representative sample of a population in order to make generalizations about the factors that influence job satisfaction. ii. This type of surveys is most suitable to study attitudes and behaviors iii. The answers are standard and uniform so that allow the researcher to do evaluation and distinction

iv. Survey results are fairly reliable and accurate
v. Surveys …show more content…

Every question in the questionnaire should be linked to the research questions and hypotheses, however, there is no commonly accepted principle of questionnaire design. There are a few suggestions from research publication of marketing for setting a general policy in order to govern every step of the design process. The process …show more content…

Probability sampling will be the most appropriate method to use if the objective of the research is to estimate the population as a whole. Zikmund (2003) stated the benefit of using the probability sampling. In this method, every member of the population has an equal chance of selection, which minimizes selection bias and improves accuracy. There are many types of probability sampling:

i. Simple random: Researchers allocate each member of the population a number and then select sample unit randomly. Samples are based on equal chance. ii. Systematic: Researchers use the natural order of sampling frame, select a random starting point, and then select items at a pre-selected interval. iii. Stratified: Researchers divide the population into groups and randomly select subsamples from each group. Variations include proportional, disproportional, and optimal allocation of subsample sizes. iv. Cluster: Researchers select sampling units randomly and survey all members in the group.
v. Multistage: Researchers select smaller areas in each stage and integrate the first four techniques above
