Importance Of Reliability In Quantitative Research

843 Words4 Pages

Quantitative research strives to present valid and reliable research finding. Du Plooy-Cilliers, Davis & Bezuidenhout (2014) points out that validity, reliability and trustworthiness is critical in the process of collecting data. For the purposes of quantitative research, validity and reliability is more suitable for this study. The aspects of validity and liability varies, and du Plooy-Cilliers, et al (2014), will explain:
4.1.1. Reliability in quantitative research
Reliability is linked to the findings of the research. In other words, it refers to the consistency of a measure. When assessing if a research method or instrument is reliable, you need to ask whether the same results would be produced if the research were to be repeated by a different …show more content…

What it is, is a measure of agreement, that uses different participants, but the same method, tool or instrument is administrated (du Plooy-Cilliers, et al. 2014).
4.1.2. Validity in quantitative research
Validity is all about determining whether the research measured what it was supposed to measure. In other words, validity is the extent to which the instrument that was selected actually reflected the reliability of the constructs that were being measured. The research instrument was tested for content validity by giving the questionnaire the managers and other employees in the fast food outlets.
This study uses a pilot study in order to increase the validity and reliability of the study. Pilot studies can be seen as mini-versions of the research (du Plooy-Cilliers, et al, 2014). A pilot test allows you test a small segment of the actual population that you will draw a sample from, but these respondents are not from the actual sample. It also allows you to determine whether the respondents understood all the questions in the questionnaire …show more content…

Ethical Considerations

Ethical considerations in research are critical. Ethics are the norms or standards for the conduct that distinguish between the right and wrong. They help determine the difference between acceptable and unacceptable behaviours (CIRT, n.d.). Ethics relate to two groups of people: those conducting research, who should be aware of their obligations and responsibilities, and the ‘researched upon’, who have basic rights that should be protected. The study therefore had to be conducted with fairness and justice by eliminating all potential risks. The respondents must be aware of their rights. Ethical issues observed in a study must include “informed consent, right to anonymity and confidentiality, right to privacy, justice, beneficence and respect for persons”.
An important consideration to take note of is that the interview schedule should be carried out when it suits the employees within the stipulated time frame. The questions asked are also transparent and have no other agenda besides that of solving the research question. Before the interview is carried out, a signed declaration is required from the participants which gives consent to use the information provided during the interview.
