Qualitative Analysis

...Chapter 2: QUALITATIVE DATA ANALYSIS If the focus of your study is the examination of documents, than you should have access to such material which may include letters, memos, notes, diaries, photographs, audiotapes, videotapes, films, articles, books, manuscripts, e-mails, online discussions and so forth. In general documents are any preserved recording of a person’s thoughts, actions or creations (Potter, 1996). The examination of documents is especially important to historians who investigate patterns and trends from the past. Documents may be examined to investigate patterns and trends of the past as is commonly done by historians. If no humans remain alive to provide primary evidence, then documents are the in only source of data (Potter, 1996). Documents are also examined by researchers who are investigating subjects who are available. The examination of documents may also provide confirmatory evidence of the information obtained from interviews and observations. For example, Bodroghkozy (1985) examined 42 letters written to her from viewers on their reaction to the TV series “Dallas”. Imagine that you want to find out what goes on in the teachers’ lounge or staff room. You could interview those involved, or maybe even send out a questionnaire. Using the interview or the questionnaire, you would be getting what people thought about what was going on. Sometimes, the best way to gain a ‘rich picture’ of a setting such as the staff room, the school......

Qualitative Research

...1. What considerations must one take into account when dealing with qualitative research? There are many considerations when dealing with qualitative research. One of the considerations I must take into account is where the information is coming from for the qualitative research (Christensen, Johnson, & Turner, 2010). The information should make sense and contain reputable or honest data. Another consideration is the data should be validated (Christensen, Johnson, & Turner, 2010). This can be done through peer-reviews to see if the data makes sense and has been known in other cases. This can also be done through other resources that have stated and proven similar facts. A third consideration is that the data is non-numerical and exploratory (Christensen, Johnson, & Turner, 2010). Many times there is some confusion between qualitative and quantitative research as qualitative research focuses on narrative or pictures while I would prefer more numerical data. 2. What factors should go into determining the sample size used in a qualitative study? When conducting research, quality sampling may be characterized by the number and selection of subjects or observations. Obtaining a sample size that is appropriate in both regards is critical for many reasons (Patel, Doku, and Tennakoon, 2003. A large sample size is more representative of the population, limiting the influence of outliers or extreme observations. A sufficiently large sample size is also necessary to produce...

Qualitative Enquiry and Qualitative Enquiry

...Qualitative enquiry adopts an exploratory orientation whereas quantitative enquiry is usually designed to find relationships among variables. How does this difference in research orientation affect the data collection and data analysis methods used for the two types of educational enquiry? Illustrate your answer with examples. Distinctive features of much qualitative research are: • ‘It tends to adopt an exploratory orientation in research design.’ (Study Guide, p. 75) Research problem is not well-defined when data are being collected. Thus, research data tend to be unstructured. • Neither numerical data nor statistical analysis is central to the data analysis. ‘Instead, the aim is to document the character of perspectives and activities of the people in the study, and/or how they employ various discourses – why these discourses take the form that they do, and perhaps also what the implications or consequences are. (Study Guide, p. 76) Thus, the choice of approach will be influenced by theoretical ideas and the methodological philosophies. The first of these orientations is strongly influenced by interpretivism. This orientation may promote the use of relatively unstructured interviews where interviewees feel relaxed and able to reveal their genuine perspectives. The second orientation ‘is concerned with finding out what actually happens in a situation as against what people say happens – what people actually do rather than what they say they......

Qualitative Critique

...Qualitative Critique Paper Neetaka Dickens University of Phoenix Analysis of Research Reports NUR/518 July 28, 2014 Veta Massey Qualitative Critique The purpose of the paper is analyze and critique the qualitative nursing research study related to a current nursing issue. A review of the strengths and weaknesses of this study and appropriateness of the studies for the clinical issue is included. While there is an impact of death on family members, there has been little research documenting the reactions and responses of our nurses. A Curtain of Protection Grief is defined as “keen mental suffering or distress over affliction or loss; sharp sorrow; or painful regret“(Merriam-Webster,2014).  Every person in the world has suffered from grief at one point or another in their life, whether it was caused by the loss of a loved one or another reason it has been felt by them.   Different people express grief in different ways; it can often bring people together as well as divide them. This is the same for our nurses. One of the nursing functions of an Intensive Care Unit (ICU) nurse is providing care for terminally-ill patients and assists them towards a peaceful death. However, in helping those patients to approach a peaceful death in an intensive care unit, nurses deal with many difficulties such as communicating bad news, counseling the persons’ families, and facilitating a peaceful death when time is limited. ICU nurses frequently face......

Qualitative and Quantitative

...D1 – Qualitative and quantitative What is qualitative? Qualitative is represented as judgment quality of something for example colour and appearance. When checking the quality of something you don’t need to measure and weight of it, so numbers are not required to identify the substances. What is quantitative? Quantitative is checking the quantity of something such as the weight, mass and area to ensure to ensure accuracy of that specific substance. By doing this you would know the exact amount/ weight of the substance or equipment that you are using. Titration: The titration that we carried out was both qualitative and quantitative. For example when we made the standard solution for the titration we used the exact quantity of the substance and we mixed it with the exact amount of deionised water (250ml) and when we were doing the calculation to get the concentration of the standard solution we made sure to use weight of the equipment that we used. When we were caring out the titration we added indicator in the base so that the solution would turn into different colour and when we add the acid into it we would be able to tell when the end point comes because the colour will change. Qualitative and quantitative comparison: I think that quantitative technique is more important than qualitative for titration because if the measurements for titration and standard solution are not accurate and precise then then it can affect all of our result and conclusion can be......

...Samantha Roberts Student Number: Word count: 1,289 There has been an ongoing paradigm debate between quantitative and qualitative research amongst social scientists for a number of years. Qualitative Research is a particularly new concept developed to obtain and analyse data however many researchers are yet to take a liking to this concept (Bryman, 1984). Qualitative research refers to studies that are conducted in natural settings and include participant observation, focus groups and in-depth interviews. (Whitley & Crawford, 2005). These techniques provide a strong insight into how participants view events and experiences to obtain a deeper meaning into the area being studied (Willig, 2001). Quantitative research focuses on the Scientific Method which is based on a series of steps that are followed systematically to acquire data such as experiments that are then analysed and presented into numerical form. This essay will examine both research paradigms while also determining the epistemological underpinnings that determines the methods used to collect and analyse data. Qualitative researchers are mainly concerned with the social world and the influence of events and experiences that has on an individual’s perspective of the world. These researchers are not concerned with answering a specific question, more so to develop a rich understanding of a certain topic mainly through the methods of in-depth interviews, participant observation and focus groups. In-depth......

...Quantitative and Qualitative Quantitative and Qualitative Research The purpose of this paper is a comprehensive comparison of quantitative vs. qualitative research techniques for MBA 5210 Business Statistics. The paper will weigh the relative merits and demerits of each providing interpretation of the potential applications of qualitative and quantitative research to various fields of study as per the requirements of the paper. Qualitative and Quantitative Overview Researchers have long debated the relative merits quantitative vs. qualitative research techniques have to offer field researchers. It is important that one understand the implications of each in order to weigh the relative importance and relevance of each to the field. Qualitative and quantitative methods have a long history of providing researchers with information regarding specific events, phenomena and subjects. The primary difference between the two forms of investigation is the methods each employs to uncover the ‘reality’ behind a given situation. These separate realities are explored below. Benz & Newman (1998) suggest that qualitative and quantitative research methods align in a continuum. Qualitative research derives its foundation in naturalistic philosophy, whereas quantitative research focuses on positivistic philosophy (Benz & Newman, 1998). Qualitative research is more likely to adopt an individual phenomenological perspective, whereas quantitative approaches tend to......

...option as well, and based on all these items, determine which option is the best for that particular situation. When analyzing a decision making of a business from an investment perspective it is important to assess it from both quantitative and qualitative information. Quantitative information refers to information that is can measure in number. It can be expressed in numerical terms including financial and non-financial information. The financial information is relating to monetary receipts and expenditures. For example, revenue, expenses, profit margins, taxes and so on. In the other hand, non-financial information means that the performance that is not expressed in monetary units, such as number of units produced, measurement of time required to make products, number of employees, number of quality return and etc. Non-financial performance measures are sometimes considered to be leading indicators of future financial performance, while current financial performance measures such as earnings or return on assets are commonly considered to be trailing measures of performance. Qualitative information refers to information that can't actually be measured, it relevant to a decision that cannot be expressed in numerical. Qualitative information is non-numerical information based on the quality of an item or object. It pertains to the description of something using our sense of sight, smell, taste, touch and hearing. For example if your customer were testing the food that......

...Qualitative Research: Clinical Scenario You are a community nurse working with Vera, an 88 year old female. She lives in her own home and has done so for 35 years but her two daughters are often present. You know the family well as you have been coming in for over a year to dress Vera's venous leg ulcer and to help manage her chronic pain from osteoporosis. Twice in the last year she has fallen and she recently fell again sustaining severe bruising to her face and left side. Both the family and (independently) Vera have suggested to you that she is finding it difficult to cope and that a spell in a nursing or residential home might be a possible solution. On your last visit, Vera's daughter stated that she is planning to broach the subject with her mother and wondered what factors Vera is likely to be considering and what areas of concern the family should expect Vera to raise when they discuss the future with her. You explain that you do not have much experience in this area, and that you would like to discuss it at the next visit after you have had time to reflect and examine the experiences of others. You formulate the question, In elderly people living at home, what are the likely issues they will be considering when deciding to seek out long-term care services? Searching terms and evidence source You decide to search the CINAHL (Cumulated Index of Nursing and Allied Health Literature) database to identify qualitative studies that have considered this topic.......

...Qualitative Research in Nursing Date of last revision : January 28, 2011 “Not everything that counts can be counted, and not everything that can be counted counts” -Albert Einstein INTRODUCTION • Qualitative research methods have become increasingly important as ways of developing nursing knowledge for evidence-based nursing practice. Qualitative research answers a wide variety of questions related to nursing's concern with human responses to actual or potential health problems. (Ploeg J, 1999) • Qualitative research is a type of scientific research which has its roots in philosophy and human sciences. • Qualitative research plays an important part in providing evidence for practice in nursing, and is gaining greater acceptance within medicine. (Bailey C, 2002) • Definition: "A quantitative approach is one in which the investigator primarily uses post-positivist claims for developing knowledge (i.e. cause and effect thinking, reduction to specific variables and hypotheses and questions, use of measurement and observation, and the test of theories)." (Creswell, 2003) • Qualitative research is used to gain insight into people's attitudes, behaviours, value systems, concerns, motivations, aspirations, culture or lifestyles. • Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior. • Qualitative research is often associated with naturalistic inquiry. • Naturalistic methods of inquiry attempt...
