Scientific research is conducted for a variety or purposes, including gathering preliminary information, to help define a scientific problem, describing a structure or phenomenon, develop new scientific methods or tools, testing a scientific theory, and to evaluate the effectiveness of a policy or program. Many methods are used for conducting scientific research. However, research can only be considered valid and “good” if it is conducted ethically. A sound research design must be aligned to its research goals, the practicalities of the research context, and meet scientific and ethical standards. Once research design is properly framed, a researcher can begin his or her research. In order to frame a research study, the researcher must identify the variables, selection of samples, schedule for data collection, and methods for statistical examination. Sound research design is critical as it directly influences the reliability of potential findings. In order to maximize information with minimal cost, time, and effort, research design must be carefully planned and organized. The theoretical and conceptual framework must tie to the research goals and purposes. If it does not, time is lost and reliability decreases. In education, mixed-method designs are most common. Reasons for mixed-method designs are plentiful. First, when a research selects either quantitative or qualitative research methodologies alone, there are limitations within each. When using mixed-methods,
The research design and methods of a study are constructed based on identifying the research problem, developing the theoretical framework, and reviewing the literature (Merriam, 2009). However, the heart of any research design, according to Maxwell (2013), is the research questions. The research questions help to focus the study and influence the choice of research design and methods for data collection. “More than any other aspect of your design, your research questions will have an influence on, and should be responsive to, every other part of your study” (Maxwell, 2013, p. 73).
Knowing the differences between a thoughtful research approach, design, and their characteristics inform the research
A research design can be understood as the planning of any scientific research from the first to the last step. In this sense it is a program to guide the researcher in collecting, analyzing, and interpreting facts (Bless and Higson-Smith, 1995:63).
This paper will review different styles of research design along with how different variables within research can be measured.

Research designs are procedures used for collecting, analyzing, interpreting, and reporting data in research studies. There are many different models with separate procedures for each of them. Research designs help guide which methods a researcher will use during their studies. When a researcher identifies an issue used for research mixed methods they choose a specific research design that best fits the problem and research questions in the study. The four basic mixed methods designs are the convergent parallel design, the explanatory sequential design, the exploratory sequential design, and the embedded design (Creswell & Plano Clark, 2006).
Researches are always carried out with the purpose of answering questions that are there, to ascertain a particular phenomenon or to prove a concept. Different researchers have different reasons for carrying out their research and this is encourage because the knowledge that is gained can be used by the others in improving that research or better understanding what the situation is. This paper tries to look at what the researchers were after and at the same trying to see the challenges they faced and their limitations. It basically tries to understand why the researchers chose the research design that has been used in the research.

I look forward to implementing my newfound knowledge of necessary characteristics of research design into my own practice and encouraging my peers to do the same in the future. My textbook by Polit and Beck (2017) and the outside supporting sources Dr. Eschiti presented will back my practices if they are ever questioned.
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;
A mixed methods research design is a procedure for collecting, analyzing, and “mixing” both quantitative and qualitative research and methods in a single study to understand a research problem.
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.
Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important.
"With the development and perceived legitimacy of both qualitative and quantitative research in social and human sciences, mixed methods research, employing the combination of quantitative and qualitative approaches, has gained popularity." (Creswell, p. 203). Describe the development of mixed methodology in educational research. Discuss the steps that need to be taken to develop a viable mixed methods research study.
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
