When undertaking clinical research there are different procedures applied to gather information with the most common methods falling into two main categories; qualitative and quantitative research. Greenhalgh & Taylor (1997) portray qualitative researchers to consider deeper issues with genuine concern in attempt to interpret the problem in terms of the way in which the participants describe them. This is achieved with a holistic methodology in a manner which reserves the natural intricacies of verbal communication. A good qualitative study will address a concern with an appropriate question, and will use iterative approaches to the methodology. These procedures often use semi-structured interviews with open-ended questions to allow the participants …show more content…
In quantitative research, the four research designs are divided by the degree in which the examiners control the variables within the experiment (Harwell, 2011). Experimental studies tend to use an intervening paradigm in which the researcher gives the participant a certain variable to deduce a reliable conclusion based on their statistical analysis of the results (Creswell, 2013). The Kato el at (2017) study was retrospective in nature, as they observed one cohort of participants who had all suffered an ACL rupture to quantify the volume of cartilage loss prior to, and one year after …show more content…
Typically, quantitative research will use complex software to analyse the variance within their data and statistics collected are represented in tables, graphs with a probability values (p-value) and confidence interval percentages (CI %) to validate the significance differences between the variables (Creswell, 2007). Kato et al primarily used tables to display their results to compare the variance of baseline and 1 one year follow-up cartilage volumes in each region of the knee. There results were validated by providing statistically significant p-values within the table and CI % within their results paragraph. Qualitative studies are narrative in presenting results by containing direct quotes from their participants. Tjong et al displayed quotes from common themes to capture the leading patient-centred themes they found within their interview process. They also utilized mixed methods within their results by displaying the comparison of patients who did and who did not return to their pre-injury level of sport in a numerical table as well as using Marx activity scores, a type of survey measuring the weekly frequency of participating in cutting and pivoting activities to quantify the activity levels of individuals who did and did not return to their pre-injury sport (Tjong et al, 2017). The use of mixed methods is
It is essential that when using evidence-based practice guidelines to choose a treatment, that variety of research methods are applied so that the best relevant data can be produced. Such methods include qualitative/quantitative research, randomised controlled trials and systematic reviews. Both qualitative and quantative methods produce valuable data. Quantative research produces numeric evidence that is necessary for practice and can be measured and qualitative research produces descriptive data about the subject by using patients views etc. which can also be applied to clinical practice (Broeder et al, 2010)

How to explore the different ways of differentiating evidence-based nursing practice and the usefulness of the process for providing the practices in the framework of evidence-based practice and nursing research studies. The most surprising information in this first five weeks is learning how to assess the theoretical- abstract components, designs in quantitative research, various methods for data collection in quantitative studies, PICO of nursing research studies and its meaning: patient, intervention, comparison and outcome. (Polit & Beck, 2014)
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.
Evidence-based practice utilizes research design analysis from arrays of studies design, it is imperative for research scholars to understand how to read, and how to comment on the quality of research design utilized. There is three major research designs, namely quantitative, qualitative and mixed method; however; mostly utilized in evidence-based practice are quantitative and qualitative. The quantitative and qualitative research designs are exclusive in the description and generate distinct outcomes. Quantitative research design explores relationship amongst independent design variables, the data compilation approach and design firmly controlled than the qualitative data compilation (Polit & Beck, 2017). The outcome of an
Richards and Schwartz (2002) listed four potential risks to research participants in qualitative studies. These are
Besides the mechanism of an injury, injuries can be distinguished by their severity. Injury severity can be defined by whether or not the athlete lost participation time (Yang et al., 2012). The National Athletic Injury/Illness Reporting Systems (NAIRS) better differentiates injury severity by classifying injuries as either time-loss (TL) or non-time-loss (NTL) injuries. Injuries that required an athlete to miss the next scheduled event/session were identified as TL injuries, while injuries that did not restrict an athlete’s ability to play we...
The purpose of research interviews is to explore the views, beliefs, and motives of individuals on a specific matter for example factors that influence their daily life. They also provide a clear understanding of social issues and an insight that is required from the participant (British dental journal, 2008).The many types of research interview in qualitative research namely are the structured, semi-structured, unstructured and in-depth interview. I will explain them further since they can be used to explore
The development of knowledge requires a number of processes in order to establish credible data to ensure the validity and appropriateness of how it can be used in the future. For the healthcare industry, this has provided the ability to create and form new types of interventions in order to give adequate care across a of number of fields within the system. Research then, has been an essential part in providing definitive data, either by disproving previous beliefs or confirming newly found data and methods. Moreover, research in itself contains its own process with a methodological approach. Of the notable methods, quantitative research is often used for its systemic approach (Polit & Beck, 2006). Thus, the use of the scientific method is used, which also utilizes the use of numerical data (Polit & Beck). Here, researches make use of creating surveys, scales, or placing a numerical value on it subjects (Polit & Beck). In the end the resulting data is neutral and statistical. However, like all things its approach is not perfect, yet, it has the ability to yield valuable data.
For everything that occurs, there will somehow be something that caused the action to happen. It is more of a cause and effect ideal or simple a reaction to an action. In terms of research academics, independent and dependent variables are concepts or attributes to certain things that occur such as drug use, crime, or domestic abuse. For example, stress or other personal problems may lead to someone to use drugs. Also, poverty may lead someone to commit crime. In addition, a power controlled individual may cause a partnership to suffer physical or verbal abuse.
This essay is going to critically discuss the advantages and disadvantages of using surveys and questionnaires as a method of Socio-Legal research. When conducting socio-legal research, a number of methods can be used to collect useful information.

Experimental designs are viewed as the most accurate, and most demanding of research designs, requiring strict attention to rules and procedures. Researchers use these research designs to manipulate and control testing procedures as a way to understand a cause and effect relationship. Commonly, independent variables are manipulated to judge or decide their effect on a dependent variable (Trochim & Donnelly, 2008).
Another characteristic of qualitative research is that it is personal and contains very little scientific terminology. For example, the researchers seek to understand human issues and problems or why humans behave in a certain manner. This type of empathetic approach in a quantitative research is a very unique in characteristic. Also, in a qualitative research, researches interact with the participants or sample, this is very important because they need to observe their behavior. As a result, it causes the research to be more up close and personal. This type of approach is what makes a qualitative research unique or different from quantitative research. (Smith &...
