Three different approaches need to be taken into consideration when conducting research, and these are the qualitative, the quantitative and the mixed-method approaches, which will be discussed further below. According to Corbin and Strauss (2014:163), the qualitative and the quantitative approaches should not be considered as the opposites of each other but rather merely as each representing a different end on a continuum.
3.4.1 Qualitative Research
The qualitative approach is a study whereby an individual or a group’s understanding and meaning is explored, as opposed to a social or human problem. Furthermore, this kind of research consists mostly of the combination of questions and procedures. The collection of the data is within the physical realm of the participants, and the analysis of the data is possible by placing the data gathered into general themes (Miles, Huberman and Saldana, 2014:154).
According to Corbin and Strauss (2014:96), qualitative research is a method that analyses data directly at the place of the case study using fieldwork observations and conducting in- depth, open-ended interviews with the sample group, as well as analysing written documents in the literature. Qualitative research mostly considers naturalistic inquiry that is concerned with understanding the real world, to be able to interpret and narrate the findings and construct a case study.
According to Salazar, Mills and Verı´ssimo (2018:81), the characteristics of qualitative research are that it aims to study and understand life in the social setting being studied, and that the methodology uses words to describe the findings rather than numbers. The common criticism of qualitative research is:
The samples are smaller and represented by a very small number of participants, which makes it difficult to generalise the results;
The findings lack attention to detail; and
It is difficult to tell if the findings are biased by the researcher’s own opinion.
On the other hand, this type of research can effectively answer questions that will assist in the study, such as why and how the particular phenomenon being studied exists. A qualitative study specifically answers questions to give answers that are rigorous. Yin (2014:332) mentions that qualitative research is a process of inquiry that deeply enquires about the understanding of social behaviours within their natural settings. It is more concerned with the question of why, rather than the questions of what. This type of research is dependant more on the daily life experiences of individuals, rather than numbers and experiments. This study focuses mainly on the following: individuals, societies and cultures, as well as language and communication.
Podesva and Sharma (2014:108) define qualitative research as the ethical consideration wherein all kinds of qualitative studies focus mostly on the meaning and content, rather than focusing on breath and scope as quantitative studies do. In a qualitative study, when collecting data different types of instruments are used such as participatory and non- participatory observation, qualitative interviews, document analysis, video recordings, as well as audio recordings. These different types of data collection have different ethical principles that always need to be adhered to, for example confidentiality and informed consent.
3.4.2 Quantitative Research
A quantitative approach deals with testing objective theories by inspecting thoroughly the relationship between two variables. The two variables that are being examined can be measured by the research instruments, for the results to be analysed using statistical methods. Those who engage in this type of research have an assumption and they want to test their theories and prevent bias in order to be able to generalise the findings of the study (Kormos and Gifford, 2014:365).
A quantitative study is defined by Yin (2014:336) as the procedure of collecting numerical data that will be analysed using mathematically based methods or statistical methods to obtain the required results. In quantitative research data is collected numerically to explain a problem (Levitt, Creswell, Josselson, Bamberg, Fros and Sua´rez-Orozco, 2018:29). According to the
Centre for Innovation Research (2015), there are four main types of quantitative research designs which need to be taken into consideration, namely descriptive, correlational, quasi- experimental and experimental designs. Each of these is discussed below:
3.4.2.1 Descriptive design
This type of design seeks to describe the status of the current problem. In this design, the researcher does not start with creating a hypothesis, instead the hypothesis is defined at the end of the study when all of the data has been collected. In most cases where this design is used the data collection occurs by observation.
3.4.2.2 Correlational design
In this design, a relationship between two variables is measured using statistical analysis, but it does not consider the cause and the effect as it is also an observational study.
3.4.2.3 Quasi-experimental Design
This type of design is also known as the casual comparative design, and it seeks to investigate the cause-effect relationship between two or more variables. For this type of design, the researcher does not have to use a group of individuals and can never influence an independent variable.
3.4.2.4 Experimental designs
This design is also referred to as true experimentation because it uses a scientific method when investigating the cause-effect relationship between the groups of variables in a study. The researcher can manipulate a certain group of variables but not the independent one, and the effects between the two variables that are dependent and independent are collected to analyse the relationship between them.
According to Flynn and Korcuska (2018:38), a quantitative research design involves a formalised principle. The data that is collected is compared with a specific variable. The collection of data is also a standardised process and the variable can only be in a numerical form and be interpreted in the form of tables, graphs or statistical measures.
3.4.3 Mixed Method Research
This type of approach involves collecting data using both quantitative and qualitative methods;
putting together two kinds of data collection methods to get results and using designs that include philosophical assumptions as well as theoretical frameworks. The advantage of using this form of research is that it gives a more complete understanding of the problem that is being researched and the results are clearer because the researcher gets an understanding of the individual participant and the group as a whole, and also gets numerical values which make it easy to interpret the results (Creswell, 2015:84).
Mixed method research i s w h e r e b y a s t u d y u s e s qualitative a n d quantitative method to collect data, analyse the data and then report on the findings (Picardi and Masick, 2014:455).
The three types of approaches have been discussed above and one has been selected to be used for this study, namely the qualitative method. This is because the study needs to gain a depth of knowledge and understanding of the individuals and groups of people within the society of KwaDabeka, to help understand if the grant that they earn is sufficient to support them, and to understand more about what the individual challenges are regarding the payment of the Old Age Grant. Qualitative research here will include the interviewing of beneficiaries to get an in- depth understanding of each beneficiary who is earning the Old Age Grant, regarding their views on the beneficial maintenance that they receive monthly. The qualitative research will seek to understand the experiences that they have encountered when going to receive their grant and how they have had handled the issues that arose.
