Confidence intervals and replication: where will the next mean fall?Geoff Cumming
School of Psychological Science, La Trobe University, Melbourne, Australia
Psychol Methods 11:217-27. 2006..4% of future replication means. The authors present figures designed to assist understanding of what CIs say about replication, and they also extend the discussion to explain how p values give information about replication...
Inference by eye: reading the overlap of independent confidence intervalsGeoff Cumming
School of Psychological Science, La Trobe University, Melbourne, Victoria 3086, Australia
Stat Med 28:205-20. 2009..Wider use of figures with 95 per cent CIs is desirable, and these rules may assist easy and appropriate understanding of such figures...- Statistical reform in psychology: is anything changing?Geoff Cumming
School of Psychological Science, La Trobe University, Melbourne, Victoria, Australia
Psychol Sci 18:230-2. 2007 - Inference by eye: confidence intervals and how to read pictures of dataGeoff Cumming
School of Psychological Science, La Trobe University, Melbourne, Victoria, Australia
Am Psychol 60:170-80. 2005..They also include guidelines for inferential interpretation of the overlap of CIs on independent group means.

Error bars in experimental biologyGeoff Cumming
School of Psychological Science and 2Department of Biochemistry, La Trobe University, Melbourne, Victoria, Australia 3086
J Cell Biol 177:7-11. 2007..Different types of error bars give quite different information, and so figure legends must make clear what error bars represent. We suggest eight simple rules to assist with effective use and interpretation of error bars...- Replication, p rep, and confidence intervals: comment prompted by Iverson, Wagenmakers, and Lee (2010); Lecoutre, Lecoutre, and Poitevineau (2010); and Maraun and Gabriel (2010)Geoff Cumming
Statistical Cognition Laboratory, School of Psychological Science, La Trobe University, Melbourne Campus, Victoria, Australia
Psychol Methods 15:192-8. 2010..2010) and Lecoutre et al. (2010), is likely to be most successful if guided by cognitive evidence and supported by resources tailored for researchers generally... - Still much to learn about confidence intervals: reply to Rounder and Morey (2005)Fiona Fidler
La Trobe University, Melbourne, Australia
Psychol Sci 16:494-5. 2005 - Impact of criticism of null-hypothesis significance testing on statistical reporting practices in conservation biologyFiona Fidler
School of Botany, University of Melbourne, Victoria, Australia
Conserv Biol 20:1539-44. 2006..Overall, results of our survey show some improvements in statistical practice, but further efforts are clearly required to move the discipline toward improved practices... - Toward improved statistical reporting in the journal of consulting and clinical psychologyFiona Fidler
School of Psychological Science, La Trobe University, Bundoora, Victoria, Australia
J Consult Clin Psychol 73:136-43. 2005..Substantially improving statistical practices may require stricter editorial policies and further guidance for authors on reporting and interpreting measures... - Reform of statistical inference in psychology: the case of memory & cognitionSue Finch
Statistical Consulting Centre, University of Melbourne, Melbourne, Victoria, Australia
Behav Res Methods Instrum Comput 36:312-24. 2004..Reform of psychologists' statistical practices would require more than editorial encouragement... - Researchers misunderstand confidence intervals and standard error barsSarah Belia
School of Psychological Science, La Trobe University, Melbourne, Vic, Australia
Psychol Methods 10:389-96. 2005..Better guidelines for researchers and less ambiguous graphical conventions are needed before the advantages of CIs for research communication can be realized... - The value of RCT evidence depends on the quality of statistical analysisCathy Faulkner
School of Psychological Science, La Trobe University, Melbourne, Victoria 3086, Australia
Behav Res Ther 46:270-81. 2008.... - Putting research in context: understanding confidence intervals from one or more studiesSue Finch
Statistical Consulting Centre, The University of Melbourne, Melbourne, Victoria, Australia
J Pediatr Psychol 34:903-16. 2009..To support wider use and higher quality interpretation of confidence intervals (CIs) in psychology... - Reducing overconfidence in the interval judgments of expertsAndrew Speirs-Bridge
School of Psychological Science, La Trobe University, Australia
Risk Anal 30:512-23. 2010..Studies 2 and 3 suggest that the 4-step procedure is more likely to reduce overconfidence than the 3-point procedure (Cohen's d = 0.61, [0.04, 1.18])... - Editors can lead researchers to confidence intervals, but can't make them think: statistical reform lessons from medicineFiona Fidler
La Trobe University, Melbourne, Australia
Psychol Sci 15:119-26. 2004..Necessary steps will include studying researchers' understanding of CIs, improving education, and developing empirically justified recommendations for improved statistical practice... - Confidence intervals permit, but do not guarantee, better inference than statistical significance testingMelissa Coulson
Statistical Cognition Laboratory, School of Psychological Science, La Trobe University Melbourne, Vic, Australia
Front Psychol 1:26. 2010..Improved statistical inference can result from encouragement of meta-analytic thinking and use of CIs but, for full benefit, such highly desirable statistical reform requires also that researchers interpret CIs without recourse to NHST...
