Understand the method. Use it with confidence.

Generate participant assignment lists (Simple/Block). Quantly runs the method against your active analysis context and returns structured results for review and interpretation.

01

When to use it

Use this tool before collecting data to plan sample size, precision, allocation, or detectable effects.
Use it only when the selected variables and study design match the method's requirements.

02

How to use it

  1. Open the tool from the Quantly Tools panel.
  2. Confirm the active dataset and analysis session.
  3. Set Total Participants (Required): The total number of subjects to randomize.
  4. Set Group Names (Required): Comma-separated list of groups (e.g., 'Treatment, Control' or 'A, B, C').
  5. Set Randomization Method (Required): Choose the method of randomization.
  6. Set Block Size (for Block Randomization) (Optional): Size of each block. Must be a multiple of the number of groups.
  7. Set Random Seed (Optional) (Optional): Set a seed for reproducibility.
  8. Review optional or advanced settings and keep defaults unless your design requires a change.
  9. Run the tool, inspect warnings and diagnostics, then save or export the result with its assumptions.
03

How to interpret results

Treat the result as a planning estimate driven by the assumptions you entered. Recalculate under plausible alternative effect sizes, variability, attrition, and significance levels.
