New Author Guidelines in Statistical Reporting: Embracing an Era Beyond p < .05

Area of Science:

• Statistics in quantitative research
• Scientific reporting standards
• Exercise science research

Background:

• The traditional reliance on p-values for statistical significance creates bias and discourages the reporting of non-significant findings.
• A dichotomous pass-fail system based on the 0.05 threshold has led to the suppression of valuable research data.
• This practice hinders the comprehensive understanding and advancement of scientific knowledge.

Discussion:

• The International Journal of Exercise Science is adopting new reporting guidelines to address statistical reform.
• These guidelines aim to move away from 'statistically significant' or 'not significant' declarations.
• Emphasis is placed on transparent reporting of raw p-values and effect magnitudes.

Key Insights:

• All p-values must be reported in their raw, continuous form.
• Measures of effect magnitude are required alongside all p-values.
• Statistical power analyses (a-priori or post-hoc) must accompany reported findings.

Outlook:

• The journal seeks to foster greater transparency in scientific reporting.
• This initiative encourages a more critical and thoughtful evaluation of research findings.
• The goal is to improve the overall quality and interpretability of quantitative research in exercise science.
