The success of the process of conducting research is largely based on the methods used to gather the information and the interpretation of resources available. In order to achieve a high degree of accuracy as well as to guarantee the substantial nature of the research process, the use of special research methods such as the quantitative and qualitative analysis is vital. However, these two methods have both advantages and limitations and, depending on the way in which these methods are used, they can provide various results.
The present paper considers the two methods of analysis as applied to a case study. In the first part, it discusses the two methods from a theoretical point-of-view. Quantitative and qualitative research are rather different in the sense that they provide different perspectives of analysis:….

On the other hand, qualitative research is process oriented and usually seeks the methods by which individuals draw certain conclusions about the information under scrutiny. It is more aligned with studies on social systems that have numerous variables and properties. There would be a search for "chain" sequences that lead to events.
Criterion five, Sampling, as previously stated has very different emphasis in either of these methods. In quantitative analysis, the bigger the better is the overall emphasis on sampling size. The more data and the larger the sample, the less the variance and the more accurate the results. This is often the opposite in qualitative research. In this venue the research often has to gather a great deal of information from individual subjects. The time involved for data collection and analysis is much greater and requires more detailed analysis of meaning. Which leads to criterion six, Analysis. Analysis is….
Qualitative vs. quantitative research
While quantitative research uses the scientific method to prove or disprove a hypothesis in a numerical fashion, qualitative research is narrative in scope and studies phenomena from a subjective, open-ended perspective. Quantitative research is deductive and proceeds from the general to the specific and usually involves studying a large population to create a general principle that can be applied to individual cases. Qualitative research studies specific cases and (sometimes) creates a general principle from those cases. Other times qualitative may be so specific and so focused upon unique cases that the research may merely present the data rather than creating a theory.
Examples of qualitative research methodologies include case studies, ethnographies, and phenomenology. Methods of qualitative researchers may include observing subjects; interviewing subjects and then coding their responses; or even participant-observer engagement with the researcher actively involving him or herself in the process of study. Qualitative grounded research….
The time-constant covariates influence the latent variable while the time-varying predictor variables influence the independent variable. In estimation of the model the start was with a 'one-class' model with progressive adding of classes and comparison of models through use of the "Bayesian Information criterion (BIC) which compared the "expected cell frequency counts with actual cell frequency counts found in the sample data." (Ibid) Stated is that improvements in model fit "were indicated by a decreasing BIC with each successive model as classes were added and completion of the model estimation was at the point the BIC showed a rise. A descriptive analysis was conducted as well which states that "overall there was a trend toward poorer levels of SRH with each successive data collection wave." (Ibid) Stated is that the unbalanced data was handled by Latent GOLD which estimated models through use of information that was available for "each….
Strengths in this study are that use of existing data saves time, costs and resources and the ability to "study larger, more representative samples and include more variables; and opportunities to examine data from a different theoretical perspective" as well as making provisions of support for primary studies in the future. (Moriarity, et al. 1999 as cited by Finnegan, Marion & Cox, 2004) Limitations of the study are stated to be are the measurement error and endogeneity. There was limited scope in measuring some of the variables of the study due to the "availability of appropriate indicators" (Ibid) Furthermore endogeneity is stated confound relationships between the time-varying predictor variables and SRH.
Nursing: Review of Quantitative Research
Quantitative esearch Critique
Vogt, Uhiyarik, & Schroeder (2007) conducted a study that compared Aquacel dressing vs. standard wound care for primary closed vascular surgical wounds. The results of the study found that there was no difference in length of stay in the hospital, complications, patient comfort, or healing time between the two wound care methods. The only difference was that the Aquacel dressing required fewer changes than conventional dressings, but that it increased the cost of care significantly. The following will analyze the methodology of the study and its conclusions in terms of clinical validity.
The design of the study was a randomized-controlled trial comparing standard dressing to Aquacel dressing for vascular surgical wounds. The study design directly reflected the intended purpose of the research, the research questions, the theoretical frame with work, previous literature, and the proposed hypothesis. All patients that participated in the study underwent elective vascular surgery.
measurements that can be ascertained objectively. They employ statistical and mathematical data analysis; gathered through such techniques as polls, questionnaires, surveys or through manipulation of already existing data via computational techniques. Quantitative research specializes on collecting numerical data and applying it across groups in general terms, or explaining a specific phenomenon (University of South California, 2016).
It can be inferred from the use of the term qualitative that this is a research method that centrally focuses on the quality of entities, including meanings and processes that are not examined or measured through experiments. esearchers employing qualitative methods emphasize the social structure and nature of reality. They examine the close relationship between the researcher and what they are studying. The situational differentials that affect research and inquiry are also examined. They place a lot of significance on value-filled inquiry aspect (University of South California, 2016).

scientific studies involve the use of quantitative research designs whose experiments are sometimes described as true science. In this case, the research designs employ the use of conventional mathematical and statistical procedures for measurement of conclusive results. Experimental designs used in quantitative research methods involves examining various aspects that are important in a study including F-ratio, analysis of variance, significant effects, and determining probabilistic equivalence. Generally, experimental designs in quantitative research utilize a standard format in order to generate a hypothesis that can be proved or rejected.
What is an F-ratio?
An F-ratio is a beneficial test statistic that is most commonly associated with ANOVA analysis. In this case, the F-ratio is utilized to test the hypothesis whose effects are regarded as real i.e. they are significantly different from each another. In an ANOVA analysis, the sampling distribution of the F-ratio must be discussed prior to presentation of the details of….

Field study research, including marketing focus groups and one-on-one questionnaires, beta-testing of a product by real consumers, and other qualitative endeavors, shows the real, lived experience of individuals, and how they will relate to the product and make a place for it in their lives. Marketing is about process -- the process of selling a product, not an end product, given that marketing must be responsive the environment and to the whims and psychology of consumers. The inductive nature of qualitative research allows for that type of flexibility. Reality is not objective: reality is socially constructed, subjective, and dependent upon individual whims. Understanding subconscious, subjective whims rather than attempting to replicate what consumers have used in the past enable marketing revolutions occur. Quantitative data may reflect reality, but qualitative data, by studying human life, can provide better clues about what people secretly desire, and what they will aspire to in….

combining qualitative and quantitative research methods can be beneficial in nursing and health science. Notably, the usefulness of mixed research methods in nursing is due to the complexity of the phenomena studied in nursing and health science. One of the major aspects of both qualitative and quantitative research methods is that they are usually associated with inductive and deductive approaches respectively (Casebeer & Verhoef, 2002). esearchers who use both methods tend to operate with a different series of assumptions regarding the world and learning methods about it.
Since qualitative and quantitative methods have varying approaches when conducting a nursing study, none of them is effective when used alone. However, the use of mixed research methods has several advantages and disadvantages that determine their strengths and weaknesses in nursing study. Combined methods of research has several advantages including offering narrative to add meaning to numbers and also use numbers to provide….

nursing research: Discussion questions
uantitative research includes descriptive, correlative, quasi-experimentational, and experimentational research (Burns 2010: 21). Descriptive research describes a phenomenon, purely and simply. Correlative research attempts to determine if there is a correlation between two types of phenomenon (such as a correlation between participation in athletic sports and overweight adolescents' decrease in BMI). uasi-experimental research may have a 'control group' in the real world (such as overweight adolescents who do not participate in sports) while experimental research actively isolates extraneous variables that could affect the result in a controlled setting. Problem-solving involves setting goals and identifying solutions while the nursing process involves planning for those interventions. The research process uses clinical studies and literature reviews to identify and prescribe specific phenomenon in a more general fashion (Burns 2010: 41)
2. Phenomenology involves a description of a particular phenomenon. Grounded theory is theory which has its roots in a specific study….
Q3. Scientific misconduct can include falsification, in which the authors of the data deliberately distort or inaccurately report the results, usually for self-interested purposes (such as to get a particular drug approved by overstating its benefits). The construction of the experiment may be manipulated to produce a specific result, such as skewing the membership of the experimental group. Fabricating involves making up data to support a specific conclusion to bolster one's reputation or achieve a specific financial end. With plagiarism, the researchers use the data of others without giving credit, and thus profit in terms of their reputation or financially from the benefits of publishing the experiment's results. The human rights of subjects must always be protected in research -- and that includes not publishing data that could result in harm to individuals, who are treated in a particular manner, based upon inaccurate data.
Q4. A simple hypothesis states the relationship between two variables. A complex hypothesis states the relationship between three or more variables. A nondirectional hypothesis states that a relationship exists between two variables. A directional hypothesis predicts the relationship between the two variables (Burns 2010: 172-173). An associative hypothesis describes phenomenon that occur together, while causal hypothesis describes one phenomenon that causes another (Burns 2010: 168). A null hypothesis states that there is no relationship between two variables (and usually the researcher wants to disprove the null hypothesis). The research hypothesis states that there is a relationship between the two variables, which the researcher is usually trying to prove.
Q5. Quantitative research attempts to accumulate numerical data about a specific phenomenon. A quantitative literature review attempts to accumulate data from a vast array of different quantitative studies, to either describe or find out specific tendencies in the types of hypotheses tested regarding the phenomenon. Of course, it is rare that all studies will reach the same conclusion, so the researchers will evaluate the quality of the studies (for example, if a study produces an anomalous result, the author of the review will likely try to determine why this is the case, such as if there was too small a sampling size). The literature review may reach a conclusion about the phenomenon, based upon statistically analyzing the data. A qualitative research study merely assesses the variety of informational studies on a particular phenomenon to paint a clearer picture of the research that has been conducted to date on the subject.
"And usually, those extra earnings are more than pocket change" (U.S. Department of Labor, 2006). A study conducted by the United States Department of Labor in 2005 revealed that the differences in weekly earnings registered by the individuals without a high school diploma and individuals possessing doctoral studies can total up to $1,012. Also, the differences are easily noticeable between consecutive levels. For instance, an individual who has finished high school but did not go to college will make about $583 per week, whereas the individual who has dropped out of college will only make $409 per week. The actual statistics are revealed in the chart below:

Human trafficking: A grounded theory approach
According to the ICE, human trafficking is one of the darkest and most heinous crimes the agency investigates. Human beings are 'smuggled' into the country and forced to operate under conditions similar to that of modern-day slavery. The sex industry, domestic workers, and so-called 'sweatshops' are all common sites of human trafficking. "Trafficking in persons is defined as: sex trafficking in which a commercial sex act is induced by force, fraud or coercion, or in which the person induced to perform such act has not attained 18 years of age; or the recruitment, harboring, transportation, provision or obtaining of a person for labor or services, through the use of force, fraud or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage or slavery" (Human trafficking, 2013, ICE).
Most victims of trafficking are young and female. By far, the….
Measurements and Instruments for a Quantitative esearch Plan
The topic for this paper is: To what extent do African-American men who live in an urban setting and exhibit aggressive behavior due to early development factors associated with depression receive a diagnosis at local medical facilities of conduct disorder as opposed to depression? In this paper, we will discuss the method most appropriate to cover this topic and provide support for its choice.
The levels of measurement that will be important for your study and why
Scientific way of measuring is important to quantitative study. Simply because quantitative information is numeric, the gathering as well as evaluation of information coming from representative samples is much more generally utilized. In the basic form, the more reflective the sampling is, the more liable it is that the quantitative evaluation will precisely as well as accurately mirror an image of the influence of the catastrophe when generalized….

Buprenorphine Induction in Primary Care
Abstract of the study provides a clear overview of the study. It introduces the uses of the buprenorphine in the primary care settings and the study grouped in the case. It provides the methodology used to study and analyze the topic. For example, it uses different methods of collecting data such as assessment, follow-ups, urine toxicology testing, and measurement of the primary outcomes associated with opioid withdrawal. The study fails to include the population size in the methodology section. It does not provide the inclusion and exclusion criteria used in the study relating to the delimitations of the study. Besides, the study does not provide the age limit of the participants in the abstract section. This information is essential as it provides objective information about the study. The study provides concise information on the study findings. This is useful in predicting the results of the….
