P Values vs Magnitude-based Inference

Will G Hopkins, Institute of Sport Exercise and Active Living, Victoria University, Melbourne, Australia. Email. Reviewer: Alan M Batterham, School of Health and Social Care, University of Teesside, Middlesbrough, UK. Sportscience 21, i, 2017 (sportsci.org/2017/inbrief.htm#pVsMBI). Published May 2017. 2017

A slideshow explaining p values, magnitude-based inference, and the American Statistical Association's policy statement on p values is now available. The slideshow has the title of the In-brief item in last year's Sportscience, P Values Down But Not Yet Out, and it represents an elaboration of that item. The slideshow will be presented at the 8th International Conference on Kinesiology in Opatija, Croatia, May 10-14.

 

Journal Impact Factors 2017

Download the workbook (28 KB) of impact factors.

As noted in a 2015 article, I have abandoned Thomson-Reuters' impact factors in favor of Elsevier's, which are derived from a bibliographic database (Scopus) more relevant to sport and exercise science, and which are freely available in a very large workbook (33 MB) at Journal Metrics. Elsevier refers to the impact factor as the CiteScore, but it is calculated in the same manner as the traditional impact factor. I have extracted the values for our journals into a user-friendly small workbook (28 KB), which has spreadsheets sorted by journal title and by 2016 impact factor. As of last year I will not be writing a full article on the impact factors.
