Evaluating And Quantitative Research Designs

Strengths to this design are it allows the development of questions for further studies. It allows for testing of the expected relationships between the variables. It also allows for drawing conclusions about the relationship.

This study will utilize a cross-sectional research design. Such a design observes behavior or attitudes that occur at a single point in time, while longitudinal studies allow observations over time. This study seeks to examine why crime occurs by asking individuals if they have ever committed a crime (point in time). In addition, it will also be utilized because it is simple and not as costly as a longitudinal design. It is not in the best interest of the research to utilize a study that will cost a significant amount of money. Also, it is important to conduct the research in a timely manner using a longitudinal design would take more time due to its complex nature. Therefore, a cross-sectional study has been utilized.

Identify any limitations or flaws in the research design. For example, is the study repeatable and objective?

Reversal design involves repeated measures of behavior in a given setting requiring at least three consecutive phases: initial baseline, intervention, and return to baseline (Cooper, 2007). As with any intervention, baseline data is a typical primary condition for beginning the process. With reversal design data is collected, until steady state responding is achieved and then intervention is begun. The condition is applied in the form of treatment and then reversal of the treatment is performed. This procedure is described as A-B-A or baseline, treatment, baseline. The operation and logic of the reversal design involves the prediction, verification, and replication of the treatment reducing the target behavior. The reversal of the

Qualitative techniques are used at the time of collection of data and the analysis of the data. Qualitative research is used to gain an understanding of why things transpire and how they occur (Cooper & Schindler, 2014). Capella University has several technique that are pre-approved that learners can utilize for their dissertations such as descriptive case studies, descriptive phenomenology, and exploratory data analysis (Capella University, 2016). This discussion will describe the differences in the designs as they relate to the Unit 7 assignment scenario.

Through the understanding of the elements involved in a research paper, a person can obtain the ability to complete good research. In research there are two questions asked; what is going on for descriptive research and why is it going on for explanatory research. The research design is simply the theory building approach to research. Although research design is the hardest part of research it is vital for research to be guided.

This chapter includes the methodology and research design of the study. The chapter is organized in the following sections: (a) research design and design appropriateness;

The research design was described fairly well; however, they could have given more information regarding the interviews and described the categorizing rubric. They stated

The following seven tables are part of a template that will guide you through the comparison of research designs assignment. The tables include:

Q3. What theories, frameworks, models or concepts may have influenced the researchers' choice of a research design? If this is not stated specifically, list any that are implied.

A descriptive qualitative research design (Beck 2012)(Polit Denise F and Beck 2012) was used to explore postnatal mothers and nurse-midwives perceptions and experiences on birthing positions. The design enabled the researcher to gain a deep understanding of the women and midwives perceptions and experiences on birthing positions assumed by women during labour and delivery. It was an explorative using semi-structured interview which allowed the researcher to explore the in-depth, rich information. The design allowed the participants to describe their perceptions and experiences in depth (Beck 2012) (Polit Denise F, and Beck, 2012).

When selecting a research approach, Creswell (2014) outlines criteria that affect the choice of one approach over another. I have already discussed how my worldview, personal experiences, and identified problem of practice and the questions affect my research. The design, methods, and audience of my emerging research will also be considered in terms of choosing a research approach.

253 Chapter 6 Evaluation Research Design: Literature Reviews & Synthesis Frequently a research question or hypothesis can be answered through secondary research, i.e., a literature review or synthesis. Both strategies requires the researcher to mine existing data sources; ―pull out‖ relevant data or information; summarize it; logically analyze and/or statistically treat it; and report results. In many instances, the issue, problem, question, etc. which prompted the idea for an evaluation study is resolved or answered by studying and reporting previous research reports in the literature or synthesizing, either logically, statistically, or both, data drawn from existing databases. In program evaluation, it is often necessary to describe or

Furthermore, the brief exposure to statistical research designs at the beginning of the course has caused me to think critically about the type of analysis I will be conducting. Despite having been unable to settle on a specific design for my intended study, the review has provided me with the tools to understand the advantages and limitations, benefits and drawbacks of the various approaches. What’s more, gaining a better understanding of the designs and methods will enable me to

The research design used in this study was correlational. The correlational design allows the determination of existence or degree of relationship between two variables. In this study gender was used as the nominal independent variable and hours spent in in Pinterest weekly was the dependent variable. The correlational research method was chosen because it allows relevant evidence to be collected and the data collected is directly related to the research question. This type of study manages variations, identifies relationships between variables, and produces answer to the research question. The purpose of the research had to reflect on the research design in order to reveal whether or not there was a statistical significance, in this case
