measures of dispersion

The creation of the Rheum4Science program grew out of the conviction that teaching science is important for rheumatologists in training and that adult learners benefit from a variety of resources and formats. Rheum4Science interactive modules teach the underlying immunology and clinical research methodology necessary for the knowledgeable practice of rheumatology. In this activity, learn about data collection and distribution, including the different research variables and how to select and interpret the best measures of central tendency and dispersion.Rheum4Science SeriesThis activity is part of a series. See the other activities in the series below.Rheum4Science: Immunology SeriesRheum4Science: Pathology SeriesRheum4Science Interactive ModulesRheum4Science – Clinical Research MethodologyRheum4Science: Data & DistributionRheum4Science: Cohort StudiesRheum4Science: Randomized Controlled TrialsRheum4Science – Immunopathogenesis of Rheumatic DiseaseRheum4Science: Pathogenesis of Rheumatoid ArthritisRegistration is complimentary. Target AudienceRheumatology fellows in training. This activity may also be of interest to medical students, residents, practicing rheumatologists, and other rheumatology health care professionals interested in strengthening their understanding of basic scientific principles and clinical research methodology relevant to the field of rheumatology.Learning ObjectivesUpon completion of this activity, participants should be able to:Differentiate types of variables (continuous, ordinal, nominal, binary, categorical)Recognize various data distributionsSelect the best measures of central tendency and dispersion for reporting common data distributionsInterpret measures of central tendency and dispersionCE & MOC InformationThis activity is not eligible for CME/MOC.Acknowledgement of Commercial SupportNo commercial support was provided for this activity.Educational Activity PoliciesSee ACR educational activity policies, including the online enduring activity refund policy.
