The aim of the article is to quantify how often in leading Czech social-science journals (Československá psychologie / Czechoslovak Psychology, Pedagogika/Pedagogy, and Sociologický časopis / Czech Sociological Review) authors choose the wrong procedures to analyse quantitative data. In particular, attention is focused on the incorrect choice of statistical tests, their misinterpretation and mechanical application, and the use of effect sizes, that are so highly recommended nowadays. The basic research period was ten years, from 2005 to 2014, and for the Czech Sociological Review the period was extended back to 1995. The results of the content analysis of published articles (N=363) show that statistical tests are applied quite often to data that are not suitable for statistical tests: this is found in about one-fifth of cases in Czech Sociological Review, one-half in Pedagogy, and more than three-quarters in Czechoslovak Psychology. In addition, authors often make mechanical use of statistical methods or make incorrect interpretations (in over 40% of articles in the Czech Sociological Review over the last 10 years) and there are rarely any substantive interpretations of results (especially in Czechoslovak Psychology). Effect sizes are applied relatively often, but there are also gaps in their usage. It is clear from the results that changes are necessary both in the teaching of quantitative methodology and publishing practices in this subject area.
Only limited data are available on body surface potential distribution during atrial activation. The aim of this study was to establish the distributions and to analyze chosen quantitative parameters of atrial isointegral maps recorded using a limited 24-lead system in a young healthy population. A total of 166 subjects underwent a procedure of body surface potential mapping. Isointegral maps during the P wave were constructed and qualitatively and quantitatively evaluated. Three types of atrial activation in individual maps were found according to the different shape of the zero isointegral line and to mutual positions of extrema. The most frequently occurring type resembled the group mean maps and was in good agreement with published data obtained from full lead systems. The highest extrema were found in the young men group, while, surprisingly, the lowest values in the young women group. All minima and the majority of maxima were recorded outside the ranges of standard chest leads. The usefulness of the limited lead system to record isointegral P wave maps was shown and new data were presented that can be useful in noninvasive evaluation of atrial pathologies., K.
