Quantitative Research Design (JARS–Quant)

The updated APA Style JARS for Quantitative Research (JARS–Quant) address quantitative studies — studies that rely on measuring variables using a numerical system.

JARS–Quant includes guidelines for manuscripts that report

  • Primary quantitative research
  • Experimental designs
  • Nonexperimental designs
  • Special designs
  • Analytic methods
  • Meta-analyses

In addition, JARS–Quant now divides hypotheses, analyses, and conclusions into primary, secondary, and exploratory groups. This should enhance the readability and replicability of the research.

Providing the information specified in the JARS–Quant guidelines should become routine and minimally burdensome, thereby increasing the transparency of reporting in psychological research.
