Credibility
Validity of the research is relative to the purpose and circumstances under which it is conducted. Validity in research concerns the truthfulness and accuracy of its findings. Validity in qualitative research is referred to as credibility. The question to be asked is whether the findings are credible and whether one can be confident in observation and interpretations. When the researcher has established confidence in the findings, the credibility notion has been met. Credibility in qualitative research equals internal validity in quantitative research.
Five methods have been suggested to assess the credibility of qualitative research: structural corroboration, consensus, referential or interpretive adequacy, theoretical adequacy,

The term transferability is equal to external validity in quantitative research. Although the main goal of qualitative research is not to generalize the findings, it is the researcher’s responsibility to provide sufficient detailed and thick description of the context under study. In this case the potential users can make comparison and judgments. Hence, the researcher must to provide accurate and complete descriptions of the context and participants to assist the reader in determining transferability. The findings of qualitative research can be applied to other settings, people and times to the extend they are similar. Transferability of a set of findings to another context depends on the similarity or “goodness of fit” between the context of the study and other contexts.
One of the strategies that can be implied in enhancing the transferability is cross-case comparisons.
There are some threats to transferability as well which includes selection effects (the fact that the constructs that are being investigated are unique to a single group), setting effects (the fact that results can be a function of the specific context), and history effects (the fact that unique historical experiences of the participants may militate against comparisons). Reactivity (the effect of the research itself) might also limit
...g the criteria noted above in the checklists proved in Houser (2015). It has been noted with evaluation that it appears to have the components of adequate criteria for being a credible source and having credible authors. The design of being a qualitative study has been evaluated and contains most of the components of the noted checklist. There are ethical issues that are well documented and weighed. The problem statement and purpose statement have been noted and the literature review was evaluated thoroughly. The sampling strategy is purposeful and explained in depth. The study was compared and is noted that its methods are of trustworthy quality. To optimize EBP is the ultimate goal in conducting a study of this nature. It has been shown that there is a significant amount of knowledge obtained from the study and there is a probable use for this information.

However, both characteristics of reliability and validity are important and can be used in many studies, such as the self-rating and other- ratings of daily behavior. Reliability refers to the internal consistency, inter-rater reliability, test-retest, and standardized scoring. In other words reliability means that study scores have to be constant with repeatability of the findings. Validity also refers to convergent validity, discriminant validity, and predictive validity. Validity refers to the reliability or credibility of the research. If the findings in a study, reliability and validity are valid they must be reliable.
Qualitative and quantitative methods allow researchers to investigate, explore and inquire the nature of the phenomenon being studied. It is important that the researcher develops a clear understanding of the problem and design a plan to investigate it (Cresswell, 1998, para. 1). There are a variety of research methods; nevertheless, it is important to consider which research method is appropriate for the study. Qualitative research focuses on human experiences while quantitative research relies on numbers, measurements, and testing. Nevertheless, qualitative and quantitative methods use similar approaches to conduct research and collect data. For example, observations and interviews are approaches used in both research designs; however, the approaches are used and viewed otherwise. This will be discussed later in the paper.
The type of data collection for a qualitative research study depends on the research design. The qualitative design itself originates out of the disciplines and flow throughout the process of research (Creswell, 2014). Creswell (2014) recommends narrative, phenomenology, ethnography, case study, and grounded theory as common qualitative research methods. These were recommended because of they are popular across the social and health and science research studies. Hays and Woods (2011) asserted that selecting a research tradition congruent with one's research orientation and study purpose, and at the same time, infusing it in all phases of qualitative inquiry, is one of the key criterions for trustworthiness of the research results. Hays and Woods (2011) recommends six qualitative research traditions, including ground theory, phenomenology, consensual qualitative research, ethnography, narratology, and participative action research. Indeed, while there are additional qualitative research methods available, scholars have identified these six qualitative traditions consistently or identified them as emerging and common methods of qualitative research (Hays & Woods, 2011).
Researchers need to understand methodology before a study is conducted in order to have a clear understanding of the research methods and for the researcher to become familiar with the research method used(Study.com, 2015). Concepts: Validity: Validity is the length to which a test measures what it claims to measure(Cherry,
Qualitative and quantitative research have many differences. Qualitative is exploratory, interpretive, subjective, descriptive, emergent, looks to produce or reach a hypothesis by what is observed, has unknown variables, is flexible, and uses personal views. Qualitative research is confirmatory, predictive, objective, deduces and test the hypothesis, has known variables, is not flexible, but is a fixed, static designed to control variables, and tries to be bias-free. Qualitative research collects data through interviews, observation, surveys, review of artifacts, and self inqu...
Qualitative research is an approach that attempts to situate an activity that locates the observer in the world by providing the study to occur in their natural setting and by attempting to make sense of, or interpret information (Denzin and Lincoln, 2005). A characteristic of qualitative research is to use a variety of empirical materials such as personal experience, interviews, and questionnaires. It is imperative to understand the task at hand and how to fully carry out the study when using a qualitative research approach in order to find out the information needed. One view of qualitative research is it involves examining individual’s experiences and documenting those experiences in detail (Jones, 2011). By documenting these observations the researcher is ensuring validity in his or her data and giving the correct creditability to those who participated in the study.

...chniques and procedures among those associated with quantitative or qualitative research. A literature review, which included document analysis, was used to answer sub-questions one, two and three. A model building approach was suggested to answer sub-question four. In addition, the study uses a case study as a proof-of-concept. The use of a case study is a qualitative empirical study to strengthen the research validity. Since the research methods directly responding to the research questions (Literature review and Model building) make use of textual data, we classified this study as a qualitative study. Table 3.1 below summarises the classification of this study in terms of the dimensions discussed above.
