When is descriptive research design used Historical case study or experimental
Types of research designThere are several types of research design which can be used depending on the nature of the research. This section gives you details of the following research designs: Show
1. Action Research Design 2. Case Study Design 1. Action Research DesignAction research consists of a family of research methodologies which pursue action and research outcomes at the same time. Action research design tends to be cyclic in nature wherein, initially an understanding of the problem is developed and plans are made for some intervention. This is followed by acting upon the interventions and then the
related observations or information is collected. This is followed by critical reflection in which This research design is thus cyclical in nature and helps in deeper understanding of a given situation starting with conceptualizing the problem followed by several interventions and their evaluations. Advantages: Disadvantages: 2. Case Study DesignCase study design is a useful tool for in depth analysis of a particular research problem rather than a statistical survey. It helps in narrowing the
research problem to a few examples. Unlike surveys, a case study will not provide complete answers to a question but it can help in elaboration and hypothesis formation. This design can also be used to test the applicability of a theory or a model in the real world. Cautions: 3. Causal DesignCausal designs are used to study phenomena in which a variation in one phenomenon (the independent variable) leads to a variation in other phenomena (the dependent variable). Causal researches are conducted in order to understand the nature and extent of cause and effect relationships. Cautions: 4. Cohort DesignCohort design is a design in which a group having similar characteristics is closely monitored over time simultaneously with another group. It is generally used in medical research where a population is
selected and information is collected on the statistical occurrence of a particular phenomenon (say heart disease) among subjects which have a particular characteristic (diabetics). The entire population is then followed up in time Advantages: 5. Cross Sectional DesignCross sectional design lacks the dimension of time. In cross sectional researches, observations are taken for different groups at one point of time. A cross sectional design can only measure differences among the subjects. A cross sectional study can be used to describe the characteristics of a group. However, the process of change cannot be traced in a cross sectional study. It focuses on finding relationship among variables at one point of Caution 6. Descriptive Research DesignDescriptive research designs are the best methods for collecting information that will demonstrate relationships or describe the current status of the phenomenon as it exists. Descriptive studies involve surveys or interviews to collect the necessary information. Descriptive studies typically provide answers to questions related to who, what, when, where
and how, however, they cannot provide answers to why. 7. Experimental DesignIn the simplest forms of experimental designs, two groups are created which are equivalent to each other. Then one of the groups, also called the treatment group gets a programme and the other group, also called the control group does not get the programme. These two groups are similar in all other aspects. Then the differences are observed in both the groups. 8. Exploratory Research Design:Exploratory research designs are used when the researcher has an understanding or observation about something and seeks to learn more about it. It is used in research problems in which there are few or no earlier studies to refer to or rely upon to predict an outcome. Exploratory designs are undertaken with one or more of the following goals:
Advantages: Caution: 9. Historical Research DesignHistorical research typically involves studying and interpreting past events to predict the future ones. Historical research typically involves Collection, verification and synthesis of evidences from the past so as to establish or refute a hypothesis. It uses both primary and secondary data sources including documentary evidences such as diaries, reports, archives, official records etc. Advantages: Caution: 10. Longitudinal Research DesignIn a longitudinal study,
the sample is followed over time to make repeated observations. In longitudinal studies, the same group or sample is tracked over time and the changes observed. The researcher then relates them to variables that might have caused the changes. They are useful in studies required to establish causal relationship and help in showing both the magnitude and direction of causal relationships. 11. Meta-analysis DesignMeta analysis is a technique designed for combining results from independent studies. It involves evaluation and summarizing of results from a number of individual studies thus increasing the overall sample size and also increasing the ability of researcher to study the effects of interest. This
type of study uses synoptic reasoning to develop a new understanding of the research problem. Meta-analysis includes analysing differences in the 12. Observational DesignThis type of research design draws a conclusion by comparing subjects against a control group; however, the allocation of treatment is not fully under the control of the researcher. The main difference between experimental and observational research is the lack of manipulation of independent or causal variable in case of observational research design. The researcher simply observes the naturally occurring values of the
independent and Caution: 13. Philosophical designThe philosophical researches challenge the assumptions underlying a particular study. Arguments derived from philosophical theories, models, concepts or traditions form the tools for this type of studies. Such studies can basically be of three types:
Advantages: Caution: 14. Sequential Research DesignA sequential design may be defined as a combination of longitudinal and cross sectional design in which several cohorts are followed at a time. In longitudinal designs, we look at one group over a long period of time and in cross sectional design we look at several groups at a particular
period of time. In sequential design, we look at different groups over a period of time. Caution: The sampling method used does not allow choosing a representative sample of the population unless the researcher goes for a very large sample. Also as the sampling technique is not randomised, the results cannot be generalised for the entire population. It is also difficult to interpret variation from one sample to another over time. Is case study experimental or descriptive?No, a case study is not an experimental study. Typically a case study is descriptive in nature. It provides detailed and in-depth descriptions of one or more cases.
Which is an example of when descriptive research designs should be used?Descriptive research is also used to compare how different demographics respond to certain variables. For example, an organization may study how people with different income levels react to the launch of a new Apple phone.
Does descriptive research have case studies?A variety of data collection methods may be used alone or in combination to answer the types of questions guiding descriptive research. Some of the more common methods include surveys, interviews, observations, case studies, and portfolios.
Is historical research descriptive?Historical research involves interpretation of facts rather than a mere amassing. Accordingly, a historical researcher does not just describe events that happened; rather it entails a description of events and the factual reasons behind their happening (Leedy & Ormrod, 2009, p. 164).
