  • Measurement science

Background:

  • Concerns regarding statistical power and replicability have prompted debate in human neuroscience.
  • Increasing sample size is a recognized method to boost statistical power.
  • Measurement precision is an equally important, yet often overlooked, factor for statistical power.

Approach:

  • This review introduces measurement precision and its significance for well-powered human neuroscience studies.
  • It elaborates on precision determinants across neuroscientific methods like MRI, M/EEG, EDA, Eye-Tracking, and Endocrinology.
  • The review discusses systematic evaluation of precision to improve reproducibility.

Key Points:

  • Statistical power is enhanced by both increased sample size and improved measurement precision.
  • Precision is fundamental to robust scientific practice in human neuroscience.
  • A systematic approach to precision can significantly benefit research outcomes.

Conclusions:

  • Enhancing measurement precision is vital for increasing statistical power and ensuring reproducibility in human neuroscience.
  • Systematic evaluation and application of precision insights across methods like MRI and M/EEG are encouraged.
  • This approach promises more reliable and reproducible neuroscience findings.
