Choosing appropriate quantitative research design

Action Research - This research is often conducted within a program, organization or community and the researchers are involved in gathering data and studying themselves. In many therapy trials it is not possible to use a placebo or achieve double blinding and in this circumstance it is crucial that every effort is made to blind the assessor to the treatments, so that the measurement of the outcome that demonstrates the effectiveness of the treatment is subject to the least bias possible.

The results from a descriptive research cannot be used to discover a definitive answer or to disprove a hypothesis. Limitations of Using Quantiative Methods Quantitative methods presume to have an objective approach to studying research problems, where data is controlled and measured, to address the accumulation of facts, and to determine the causes of behavior.

Also included is a collection of case studies of social research projects that can be used to help you better understand abstract or complex methodological concepts. Delimitations are set so that your goals do not become impossibly large to complete.

Types of Research Designs. Colorado State University; Singh, Kultar. The descriptive function of research is heavily dependent on instrumentation for measurement and observation.

Experimental research is often used where there is time priority in a causal relationship cause precedes effectthere is consistency in a causal relationship a cause will always lead to the same effectand the magnitude of the correlation is great. Note that your research problem determines the type of design you should use, not the other way around.

There are no hidden controls or preemption of direction by the researcher. Basic Inquiry of Quantitative Research. The focus is on gaining insights and familiarity for later investigation or undertaken when research problems are in a preliminary stage of investigation.

There is no follow up to the findings. Also, remember that whatever limits you also limits other researchers, whether they are the largest medical research companies or consumer habits corporations. What these studies don't tell you.

The methods section should be presented in the past tense. Can you complete the entire study with one data collection session. This would give you a very good idea of the variety of ideas and feelings people have, it would enable them to think and talk for longer and so show their feelings and views more fully.

Delimitations are often strongly related to your theory and research questions. Developing and using a questionnaire - some tips: What might they prevent you from discovering. However, the research designs identified in this document are fairly common in terms of their use and their terminology.

One of the key features of an experimental design is that participants are randomly assigned to groups. Qualitative methods are chosen when the goal of the research problem is to examine, understand and describe a phenomenon. Wadsworth Cengage, ; Muijs, Daniel. However, being able to recognize and accurately describe these problems is the difference between a true researcher and a grade-school kid with a science-fair project.

These are choices you will need to make, both for practical reasons i. Key Considerations There are a number of factors that will guide your choices regarding study design.

While longitudinal studies involve taking multiple measures over an extended period of time, cross-sectional research is focused on finding relationships between variables at one moment in time. The limitation is that the sources must be both authentic and valid.

Sage,pp. If you used a common test for data findings, your results are limited by the reliability of the test. Giving students an assessment of knowledge the first day of class and giving the same assessment on the last day of class is an example of a research design based on a single-sample repeated measures.

Organizing Your Social Sciences Research Paper: Types of Research Designs

The protocol is iterative or cyclical in nature and is intended to foster deeper understanding of a given situation, starting with conceptualizing and particularizing the problem and moving through several interventions and evaluations.

With this in mind, a common mistake made by researchers is that they begin their investigations far too early, before they have thought critically about what information is required to address the research problem.

Are there sampling issues that get in the way of my being able to generalize my findings. This is applied to the control group in the experiment.

The researcher will then develop a research problem related to the topic and create a specific question. HOW TO CHOOSE FROM THE DIFFERENT RESEARCH METHODS* Quantitative Research is highly recommended.

Selecting the correct type from the different research methods can be a little daunting, at researcher recognizes and evaluates flaws in the design when choosing from different. The research design refers to the overall strategy that you choose to integrate the different components of the study in a coherent and logical way, thereby, ensuring you will effectively address the research problem; it constitutes the blueprint for the collection, measurement, and analysis of data.

research design is also based on the nature of the research problem or issue being addressed, the researchers’ personal experiences, and the audiences for the study. THE THREE TYPES OF DESIGNS quantitative research, for example, starts with the test of a theory.

3. Data, evidence, and rational considerations shape knowledge. The research question, ethics, budget and time are all major considerations in any design.

This is before looking at the statistics required, and studying the preferred methods for the individual scientific discipline.

Basic Research Designs

Every experimental design must make compromises and generalizations, so the researcher must try to minimize these, whilst remaining realistic. These elements of quantitative research drive the decisions regarding research methodologies and procedures related to choosing an appropriate research design.

The following is a brief overview of the research designs used in social sciences. Many different quantitative and qualitative research designs exist, each with a specific purpose and with strengths and limitations.

In this editorial, the most rigorous quantitative designs to address questions of prevention or treatment, causation, and prognosis will be outlined.
