Ch. 6 Observational/Descriptive MethodsThe subject is being observed in a completely natural and unchanged natural environment.There are two serious problems with case studies — expectancy effects and atypical individuals.Qualitative description is a useful qualitative method in much medical research if you keep the limitations of the approach in mind.
The design can provide detailed descriptions of specific and rare cases.This leads to greater ecological validity than laboratory observation, proponents say.It is generally not expensive, time consuming, or workforce intensive.Laboratory observations are usually less time-consuming and cheaper than naturalistic observations.It is important to emphasize that descriptive research methods can only describe a set of observations or the data collected.Cross-section studies are capable of using data from a large number of subjects and, unlike observational studies, is not geographically bound.Justification of the techniques used to evaluate the studies.
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.It is often used to narrow down a very broad field of research into one or a few easily researchable examples.
The researcher has a limitless option when it comes to sample size and the sampling schedule.Permits the researcher to identify cause and effect relationships between variables and to distinguish placebo effects from treatment effects.Because the research design can be very complex, reporting the findings requires a well-organized narrative, clear writing style, and precise word choice.The purpose of this guide is to provide advice on how to develop and organize a research paper in the social sciences.There is greater confidence the study has internal validity due to the systematic subject selection and equity of groups being compared.Of course, both naturalistic and laboratory observation are important in regard to the advancement of scientific knowledge.
Analytical Method - Tool/Concept/Definition - Thwink.orgObservational Method With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed.True experiments must have control, randomization, and manipulation.
Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.If the criteria for selecting a case is because it represents a very unusual or unique phenomenon or problem for study, then your intepretation of the findings can only apply to that particular case.
Social scientists, in particular, make wide use of this research design to examine contemporary real-life situations and provide the basis for the application of concepts and theories and the extension of methodologies.
