(wikipedia.org)
  • His interests continue to be focused on scientific methodology with a blend of mathematics, social sciences like Psychology, philosophy of science and measurement in science. (wikipedia.org)
  • His research has branched to many areas in statistics, measurement, and scientific methodology. (wikipedia.org)
  • He takes a problem-solving point of view to his research in that the research is not tied to any one area of statistics or measurement. (wikipedia.org)
  • As is evident from the list of publications and awards, his program of research is noted for his having addressed cross-disciplinary recurring controversial topics such as theories of measurement validity, measurement invariance, the role of levels (or scales) of measurement in statistics, and the role of hypothesis testing in empirical studies and particularly their lack of robustness to violations of assumptions. (wikipedia.org)
  • His contributions to these debates have highlighted his orientation from the intersection of mathematics, measurement and statistical science with consideration given to philosophy of science and scientific methodology. (wikipedia.org)
  • In that article, Stevens claimed that all measurement in science was conducted using four different types of scales that he called "nominal," "ordinal," "interval," and "ratio," unifying both "qualitative" (which are described by his "nominal" type) and "quantitative" (to a different degree, all the rest of his scales). (wikipedia.org)
  • median
  • In place of means and standard deviations, univariate statistics appropriate for ordinal data include the median, other percentiles (such as quartiles and deciles), and the quartile deviation. (wikipedia.org)
  • social
  • This study calls attention to the long-range difficulties that head-injured battered women may experience as a result of cognitive, emotional, and behavioral difficulties resulting from domestic violence and how social workers can intervene with this population. (thefreelibrary.com)

(wikipedia.org)
  • Gill is an expert in these statistical and computational techniques and uses them to contribute to empirical knowledge in the biomedical and social sciences. (wikipedia.org)
  • Their training in both social science and quantitative methodology provides a unique skill set for solving both applied and theoretical problems in a variety of areas. (wikipedia.org)
  • analysis
  • All possible polarity configurations were then compared, and a statistical analysis was used to determine whether, for a given synaptic class, a particular polarity was associated with a good fit to behavioral data. (jneurosci.org)

  • Krippendorff's alpha generalizes several known statistics, often called measures of inter-coder agreement, inter-rater reliability, reliability of coding given sets of units (as distinct from unitizing) but it also distinguishes itself from statistics that are called reliability coefficients but are unsuitable to the particulars of coding data generated for subsequent analysis.

  • With an eye to fostering his talents and interests, the University of Alberta allowed him to take graduate (Masters and PhD) courses in statistics and mathematics while eventually completing his B.Sc. (wikipedia.org)
  • standard
  • Stevens (1946) argued that, because the assumption of equal distance between categories does not hold for ordinal data, the use of means and standard deviations for description of ordinal distributions and of inferential statistics based on means and standard deviations was not appropriate. (wikipedia.org)
  • means
  • The ANOVA produces an F-statistic, the ratio of the variance calculated among the means to the variance within the samples. (wikipedia.org)
