In general, there are three primary reasons to conduct descriptive studies: To identify areas for further research.
|What is a Case Study?||We already know that going into the survey design phase with research goals is critical, but how do we know that our research plan will provide fruitful information.|
|This article is a part of the guide:||Descriptive Research Method descriptive research Descriptive research, also known as statistical research, describes data and characteristics about the population or phenomenon being studied. Descriptive research answers the questions who, what, where, when and how A form of conclusive research that aims to describe a product or market or identify associations among variables.|
Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: This article will briefly describe each of Descriptive research study methods, their advantages, and their drawbacks.
This may help you better understand research findings, whether reported in the mainstream media, or when reading a research study on your own.
Observational Method With the observational method sometimes referred to as field observation animal and human behavior is closely observed.
There are two main categories of the observational method — naturalistic observation and laboratory observation. The biggest advantage of the naturalistic method of research is that researchers view participants in their natural environments.
This leads to greater ecological validity than laboratory observation, proponents say.
Ecological validity refers to the extent to which research can be used in real-life situations. Proponents of laboratory observation often suggest that due to more control in the laboratory, the results found when using laboratory observation are more meaningful than those obtained with naturalistic observation.
Laboratory observations are usually less time-consuming and cheaper than naturalistic observations. Of course, both naturalistic and laboratory observation are important in regard to the advancement of scientific knowledge.
Case Study Method Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
There are two serious problems with case studies — expectancy effects and atypical individuals.
Describing atypical individuals may lead to poor generalizations and detract from external validity. Survey Method In survey method research, participants answer questions administered through interviews or questionnaires.
After participants answer the questions, researchers describe the responses given.
In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend. Another consideration when designing questions is whether to include open-ended, closed-ended, partially open-ended, or rating-scale questions for a detailed discussion refer to Jackson, Advantages and disadvantages can be found with each type: Open-ended questions allow for a greater variety of responses from participants but are difficult to analyze statistically because the data must be coded or reduced in some manner.
Closed-ended questions are easy to analyze statistically, but they seriously limit the responses that participants can give. It is important to emphasize that descriptive research methods can only describe a set of observations or the data collected. It cannot draw conclusions from that data about which way the relationship goes — Does A cause B, or does B cause A?
Nothing could be further from the truth. Research Methods and Statistics: A Critical Thinking Approach 3rd edition. Jamie has written seven books and co-authored one.Descriptive research is used to describe characteristics of a population or phenomenon being studied. It does not answer questions about how/when/why the characteristics occurred.
Rather it addresses the "what" question (what are the characteristics of the population or situation being studied?). Descriptive Study. A descriptive study design is one in which your primary goal is to assess a sample at one specific point in time without trying to make inferences or causal statements.
In general, there are three primary reasons to conduct descriptive studies: To identify areas for further research.; To help in planning resource allocation (needs assessment).
There are three basic types of questions that research projects can address: ashio-midori.com a study is designed primarily to describe what is going on or what exists. Descriptive research can be explained as a statement of affairs as they are at present with the researcher having no control over variable.
Moreover, “descriptive studies may be characterised as simply the attempt to determine, describe or identify what is, while analytical research attempts to. In this talk, Assistant Professor Abraham Flaxman explores the methods underlying morbidity estimations in the Global Burden of Disease (GBD) study, as laid out in the new book An Integrative Metaregression Framework for Descriptive Epidemiology, published by the University of Washington Press..
