Validity means that the study investigates what was intended, reliability refers to the con-sistency of findings/results, whether the results are repeatable and generalization means that findings can be generalized to other settings (Fink, 2000). Qualitative validity according to Creswell (2003) means that the researcher should check for accuracy of the findings. One of the main strategies to assure validation is triangulation is the process of comparing different kinds of data or data derived from different methods (Lincoln & Guba, 1985).
Qualitative reliability indicates that the approach of the researcher is consistent in dif-ferent projects Creswell (2003) suggests that in order to determine if the researcher 's ap-proaches are consistent,

More frequent in qualitative research is to generalize to theory rather than to population, it is looking for a system that their findings are included in it. In other words, the quality of the theoretical inferences that derive from the data, is the important issue when generalizing (Bryman, 2009)
Janesick (2000) suggests alternative ways to think about the trinity of validity, reliabil-ity and generalization, in fact he offers to change the language to a more accurately describes the complexity and texture of qualitative research. He also argues that “the traditional view of generalizability limits the ability to reconceptualize the role of social science in education and human services” (p.

Semi - structured interview – the interviewer has general form of interview schedule, but he can vary the sequence of the question and add questions to significant replies (Bryman, 2009).
3. Unstructured interview – the format is non – standardized, the interviewer has only list of topics, like an interview guide, and he uses an informal style in order that the problem of in-terest will arise from the interviewee 's reactions. (This type of interview often called: Inten-sive interview or ethnographic interview) (Bryman, 2009; Denzin & Lincoln, 2000).
4. Qualitative interview – general term for both the Semi – structured and the unstructured interview (this type of interview often called: In - depth interview), the purpose of in-depth interview is to examine assumptions rather than to get answers; it is based on the willing to understand the experience of other people and the significance that they attached to it (Bryman, 2009).
5. Focused interview – an interviewees are selected to be interviewed due to their involve-ment in a particular situation and are asked about that involvement, it may be administered to individuals or to groups (Bryman,
1. How are reliability and validity related to each other? Why is each important? (60-80 words) Reliability and validity are concepts that go hand in hand. These concepts are related to each other and they are needed to keep the quality of assessments.
307). Fittingness, credibility, and auditability will be a better fit and more appropriate for qualitative studies (LoBiondo-Wood & Haber, 2014, p. 125). Fittingness gives a detailed description of the participants’ daily lives to prove the relevance of the research findings and can be used for relatable research and theory development (LoBiondo-Wood & Haber, 2014, p. 126). When adequate information is provided for the evaluation of data analysis, an accurate and in depth description of research findings are made which demonstrates fittingness. Credibility allows the researcher to verify their interpretations and accuracy of their perspective by returning for further interviews with the participants (LoBiondo-Wood & Haber, 2014, p. 126).
If I, was to go to Harper High School, I would use credibility, transferability, dependability, and confirmability to make my findings valid. Credibility, focuses on making sure that the interpretations presented in the study are true to the observed (168-170). The purpose of qualitative research is to describe the perspective from the participant 's eyes, thus, the participants are the only ones who can legitimately judge the credibility of the results. Since, I would be conducting similar research to the radio producers, seeing the daily activities of the students would help establish credibility, since it is direct data. Transferability, is a response to generalization (done by quantitative research), it creates ‘thick description’ which is detailed description of the research and assumptions (168-170).
Through these in depth interviews it’ll give a better grasp which will seek individual experiences and learn about their perspectives on the issues given to them. Interview
In-depth interviewed are commonly used in qualitative method research.
Each individual who comes to participate for the in person interview or survey must be treated the same to decrease the chances of the interviewees words or action to influence a participant to think differently. The interviewees must be prepared and
The quantitative research that I will critique, is about the effectiveness of proton pump inhibitors (PPI) in reducing the risk of gastric injury in elderly patients who undergo an aspirin regimen. According to the study, over 50% of elderly patients who had taken either a Non-steroidal anti-inflammatory drugs (NSAID), or aspirin for less than 30 days presented some type of gastro intestinal (GI) lesion (cite). This very high number causes concern, since aspirin and NSAID’s are commonly used medications to treat, and prevent a variety of conditions. The study aims to answer two questions, the first is the risk of ulcers linked to the acute or chronic use of aspirin, and/or NSAIDs. The second question is the efficacy of anti-acid secretory treatments on these ulcers (cite).
Interviews are usually open-ended question formatted used without assumption in order to gain information. Interviews are meant to be friendly and loose in structure whereas, interrogations are meant as times to put the person being interviewed at a psychological disadvantage. Interrogations have a controlled and directed format; they have an assumption of guilt and are used for suspects. Examples of interrogation techniques are the good cop bad cop, PEACE and the Reid. The Reid Technique is a nine step process which will be further examined in the later.
Qualitative Research Appraisal Mounica Soma Texas State University Completed in partial fulfillment of the requirements for HA 5301: Healthcare Administration Research Methods October, 2015 Introduction: The article titled “Family Physicians’ Perceptions on How They Deliver Cost-Effective Care” presented a study on the effects of family physician availability on healthcare costs and outcomes. Primary care family physicians play an important role in the provision of comprehensive, integrated, accessible healthcare services that satisfy the needs of patients (WHO, 2003). A review of Starfield et al (2005) has shown that health is better in areas with more primary care physicians, people
Validity:? Are the findings relevant for other contexts?? Are the findings transferable?
As quantitative data would not be robust enough to explain complex issues. for e.g. Quantitative data would not allow children to explain their choices. However, qualitative data has some disadvantages in this research. For example, because of the central role played by Corsaro in the generation of data, it is not possible to replicate qualitative studies. Also, contexts, situations, events, conditions, and interactions cannot be replicated to any extent.
Scientific descriptions must be more precise than the cursory observation. The qualitative nature of social science research means that that this information will be utilized in order to draw larger conclusions, determining patterns and their meanings (Babbie, 2017). The explanatory component seeks to address the why in sociology research.
1999 cited in Tobin and Begley, (2004) Rigour is use to express integrity and competence in the qualitative research process. The absence there of, places the research in the fictional category of journalism, thus rendering it useless to enhance education (Morse et al. 2002 cited in Tobin and Begley, 2004). Many questions were raised about trustworthiness in qualitative research by the positivists, since it was noted that there were challenges to the concepts of validity and reliability in researches carried out in its natural surroundings.
What is Reliability and Validity? Reliability is the degree to which an assessment consistently measures whatever it measures (John, 2015). The students can be tested through whatever that they are measure with, as long as everyone have at least the same score no matter when or where they take the test.
3. QUALITATIVE RESEARCH THEORY 3.1 QUALITATIVE RESEARCH Qualitative research is a form of research in which the researcher collects and interprets data, meaning the researcher is as important in the research process as the participants and the data they provide. Reason and Rowan (2004) have argued that the core element of a qualitative research approach is to connect meanings to the experiences of respondents and their lives. According to Clissett (2008) qualitative research involves a variety of research methods that can be used to explore human experience, perceptions, motivations and behaviours. Qualitative research is characterised by collection and analysis of words in the form of speech or writing.
