Research Design Methods And Research

According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers

Qualitative research is subjective data and is often used in the social sciences (Sarantakos 2013, p. 48). Qualitative research is devoted to gathering facts, this can be completed through personal experiences, behaviours, and observations (Sarantakos 2013, p. 46). The purpose of qualitative research is to gather an in depth understanding of human behaviour and the explanations for the behaviour (Martijn & Sharpe 2006, p. 1). An issue with only using a qualitative method is efficacy, qualitative studies cannot address relationships between variables with the degree of accuracy that is required to establish social trends (Sarantakos 2013, p. 46).

According to Wyse (2011) from Snap Surveys, qualitative Research is primarily exploratory research. It is used to gain an understanding of underlying reasons, opinions, and motivations. It provides possible answers into the problem or helps to develop ideas or hypotheses for potential quantitative research. Qualitative Research is also used to find trends in

There are different ways in which researcher defines quantitative and qualitative research. Quantitative research is a social research that uses experimental methods, questionnaires, numerical data and explains observations usually in tables or charts from. Quantitative research can define the relationship between two or more studies.

A research design that is qualitative is done through the method of subjectively perceiving the qualities of a phenomenon that may not be measured quantitatively. "Qualitative research is used to examine subjective human experience by

In my research, I am going to use the qualitative method design. This method will allow me to conduct my study by means of interviews, observations, field investigations, and questionnaires. Research is something you agree to explore and find responses. Research question is the initial step that activate the research. Connelly (2015) asserted that a research question emphasizes on the topic that is designed for study, who were under study, and what the researcher intended to learn about them. Research question must be answered by agreeing and deciding the appropriate way to respond to questions. Collection of information that satisfy the research is necessary; finally findings must be presented to others.

Research design is the approach that the researcher utilizes apparatuses of a study to collect, analyze, and interpret data. There are three types of research designs: (a) qualitative – captures the description of the event that is taking place by the means of interviews and observation; (b) quantitative – employs statistical measures to interpret data taken from surveys; and (c) and mixed method – uses both qualitative and quantitative designs for an more in-depth study (Creswell, 2014; Stangor, 2014). This paper will focus on the comparison and contrast qualitative and quantitative design in relation to the selected journals.

Qualitative research uses the form of an interview with open-ended questions for researching and understanding attitudes, opinions, feelings and behaviors of an individual or groups. Qualitative research is concerned

Firstly, qualitative and quantitative research methods are used for different purposes. Quantitative methods try to explain and make predictions, confirm and validate an existing practice/model, and test a theory. The goal is to seek for the generalization of an explanation to other persons or settings. On the other hand, qualitative methods try to describe, explain and interpret complex situations. Also, they may utilize observations as a way to building a theory. For instance, when we would like to analyze the social-emotional behavior of a child through observation or parent’s interview we will implement qualitative research. Whereas, if we would like to study the effectiveness of a teaching method we would use quantitative research. Therefore, the quantitative research process differs from the qualitative. In quantitative studies, the guidelines have been designed before research’s conduct. The methods are preplanned and the researchers try to be detached from the participants and the phenomena to avoid biases. In qualitative studies, the researchers use holistic methods; the design, the measurement tools as well as the interpretations are

The article of focus for the purposes of this task is "Influence of perceived co-worker involvement and supervisory support on job satisfaction." (Okediji, Etuk, & Nnedum, 2011) The authors tested hypotheses charting the relationship among several factors that contribute to job satisfaction. The participants of the study were employees of a brewery and were selected at random. There were equal numbers of males and females. The ages of participants spanned ages 18 40. The empirical study confirmed both the hypotheses of the researchers regarding job satisfaction, co-worker involvement, and supervisory involvement during the working day. The authors explain, "Job satisfaction is more simply conceived of as the response of an individual to the condition of work, as these perceptions are shaped by objective differences in work conditions and different interpretations of the conditions." (Okediji, Etuk, & Nnedum, 2011)

The research design can be better described as the strategy that will be applied to answer the research questions. The most important thing in research design is to make clear the objectives deriving from the research question and at the same time pointing out the sources from which you aim to collect the data. It is essential to include the limitations you should probably need to override during the whole process. In that stage it is also necessary to decide which tactic will be followed. Decisions about tactics will involve you being clear about the different quantitative and qualitative data collection techniques (for example, questionnaires, interviews, focus group, published data) and subsequent quantitative and qualitative data analysis procedures (Saunders, et al., 2007).

A sample is a set of data drawn from the population, it is considered as a subset. Populations are defined as the set of all items or individuals of interest. Samples are less time consuming than a census, less costly to administer than a census and it is possible to obtain statistical results of a sufficiently high precision based on samples. There are two types of sampling techniques, probability and non-probability sampling.

This is the type of research design in which oral data is collected instead of dimensions. After this, the material that is gathered is evaluated in the manner that is subjective, interpretative, and diagnostic. Qualitative research design is the method in which researchers gather data

The three most common qualitative research designs, explained in detail in their respective modules, are in-depth interviews, participant observation, and focus groups. Each of the methods is particularly suited for obtaining a particular type of data.

We will recruit a total of 200 rural-to-urban migrant pregnant women from the People’s hospital of Tianhe District, the People’s Hospital of Baiyun District, the People’s Hospital of Fanyu District, and the People’s Hospital of Huangpu District. Since all women who attend the ANC in those hospital will be asked to complete basic information including if they are permanent residency, then we will ask health workers to provide rural-to-urban migrant women who get pregnant and attend ANC in those four hospitals with the questionnaire. Information will be collected about demographics, the period of trimester pregnancy and knowledge about ANC. We hope to recruit 50 participants in each hospital so that we will recruit 200 participants to complete the questionnaire.
