When people were asked “All in all, are you satisfied or dissatisfied with the way things are going in this country today? ” immediately after having been asked “Do you approve or disapprove of the way George W. Bush is handling his job as president? ”; 88% said they were dissatisfied, compared with only 78% without the context of the prior question. With widespread internet use, phenomenally large number of publications, training and media resources are available but determining the quality of this literature is difficult for a busy physician.
Purpose of Descriptive Research Design
It also measures the cause-effect relationship on a particular group of interest. Your research design must include ways to minimize any risk for your participants and also address the research problem or question at hand. If you cannot manage the ethical norms along with your research study, your research objectives and validity could be questioned.
Descriptive Research Design – Types, Methods and Examples
Instead, one can only calculate the odds of association between exposure and outcome. Descriptive (or nonanalytical) studies, as the name suggests, merely try to describe the data on one or more characteristics of a group of individuals. These do not try to answer questions or establish relationships between variables. Examples of descriptive studies include case reports, case series, and cross-sectional surveys (please note that cross-sectional surveys may be analytical studies as well – this will be discussed in the next article in this series). Examples of descriptive studies include a survey of dietary habits among pregnant women or a case series of patients with an unusual reaction to a drug. The main purpose of descriptive research design is to describe and measure the characteristics of a population or phenomenon in a systematic and objective manner.
Step 1: Consider your aims and approach
Probability sampling is the most statistically valid option, but it’s often difficult to achieve unless you’re dealing with a very small and accessible population. Having worked through all of these potential research designs, you’d be forgiven for feeling a little overwhelmed and wondering, “But how do I decide which research design to use? While we could write an entire post covering that alone, here are a few factors to consider that will help you choose a suitable research design for your study.
Case selection in qualitative research
There are various sampling methods you can use to ensure that your sample is representative of the population as a whole. There are many other ways of analysing qualitative data depending on the aims of your research. To get a sense of potential approaches, try reading some qualitative research papers in your field. In qualitative research, your data will usually be very dense with information and ideas. Instead of summing it up in numbers, you’ll need to comb through the data in detail, interpret its meanings, identify patterns, and extract the parts that are most relevant to your research question. In quantitative research, you’ll most likely use some form of statistical analysis.
Insufficient or Incorrect Statistical Analysis
Include a statement in your manuscript about any perceived limitations, and how you considered them while designing your experiment and drawing the conclusion. The research problem statement must be clear and to do that, you must set the framework for the development of research questions that address the core problems. Usually, researchers miss out on checking if their hypothesis is logical to be tested. If your research design does not have basic assumptions or postulates, then it is fundamentally flawed and you need to rework on your research framework. This type of experimental research is commonly observed in the physical sciences.
Most social scientists seek causal explanations that reflect tests of hypotheses. Causal effect (nomothetic perspective) occurs when variation in one phenomenon, an independent variable, leads to or results, on average, in variation in another phenomenon, the dependent variable. The selection of a specific research design method should align with the research objectives, the type of data needed, available resources, ethical considerations, and the overall research approach. Researchers often choose methods that best suit the nature of their study and research questions to ensure that they collect relevant and valid data.

The randomized controlled clinical trial is considered the gold standard for evaluating the efficacy of a treatment. Randomization leads to equal distribution of known and unknown confounders between treatment arms; therefore, we can be reasonably certain that any difference in outcome is a treatment effect and not due to other factors. It is possible to determine risk of the outcome in each treatment arm accurately. However, randomized controlled trials have their limitations and may not be possible in every situation. For example, it is unethical to randomize participants to an intervention that is likely to cause harm—e.g., smoking.
Before you can start designing your research, you should already have a clear idea of the research question you want to investigate. In diagnostic research, the design strives to explore the reason behind an issue and find solutions to solve it. This type of research design tries to solve the problems in a structured form divided into three phases- the issue’s inception, diagnosis of the issue, and solution for the issue. Research design, when done right, can generate similar results every time it is performed.
Research design involves choosing the right methodology, selecting the most appropriate data collection methods, and devising a plan (or framework) for analyzing the data. Then the intervention is carried out [the "action" in action research] during which time, pertinent observations are collected in various forms. The new interventional strategies are carried out, and this cyclic process repeats, continuing until a sufficient understanding of [or a valid implementation solution for] the problem is achieved. Research study designs are of many types, each with its advantages and limitations. The type of study design used to answer a particular research question is determined by the nature of question, the goal of research, and the availability of resources.
It involves collecting data that describe the current status or condition of the population or phenomenon of interest, without manipulating or altering any variables. This involves collecting data over an extended period of time, often through repeated observations or surveys of the same group or population. Longitudinal studies can be used to track changes in attitudes, behaviors, or outcomes over time, or to investigate the effects of interventions or treatments. A blueprint of the procedure that enables the researcher to maintain control over all factors that may affect the result of an experiment. In doing this, the researcher attempts to determine or predict what may occur. The classic experimental design specifies an experimental group and a control group.
Practice gets outdated, if not updated with current evidence, depriving the clientele of the best available therapy. The research design process is a systematic and structured approach to conducting research. The process is essential to ensure that the study is valid, reliable, and produces meaningful results. When we discuss a strategy to collect, study, and evaluate data, we talk about research design. This design addresses problems and creates a consistent and logical model for data analysis.
Descriptive statistics can include measures of central tendency (e.g., mean, median, mode) and measures of variability (e.g., range, standard deviation). A researcher must clearly understand the various types to select which model to implement for a study. Like the research itself, the design of your analysis can be broadly classified into quantitative and qualitative. By following the steps of research design, researchers can ensure that their study is well-planned, ethical, and rigorous. Research design is the framework of research methods and techniques chosen by a researcher to conduct a study.
