Consistency Score Var-Index

Measure player reliability using coefficient of variation. Identify safe floors vs. high ceilings for smarter lineup and trade decisions.

1. Player & Weekly Scores

Player Name

Position

Weekly Scores (comma or space separated)

Enter at least 3 weeks for meaningful results. Example: 18.5, 22.3, 15.1

What is Var-Index? The coefficient of variation (CV) measures how spread out weekly scores are relative to the average. Lower CV = more consistent (safe floor), higher CV = more volatile (high ceiling).

What Is the Var-Index Consistency Score?

The Var-Index (Coefficient of Variation) measures how consistent a player's weekly fantasy scores are relative to their average. It's the most reliable way to identify:

🏠 Safe Floor Players: Low Var-Index (under 15%) — reliable weekly production
🎲 High Ceiling Players: High Var-Index (over 25%) — boom-or-bust potential
⚖️ Balanced Players: Moderate Var-Index (15-25%) — steady with occasional spikes

How the Var-Index Is Calculated

📐 Formula

Var-Index = (Standard Deviation ÷ Mean) × 100

Where Standard Deviation measures how spread out scores are from the average.

📊 Worked Example

Scores: 18.5, 22.3, 15.1, 28.7, 12.4, 19.8, 16.2, 24.1
Mean: 19.6 PPG
Std Dev: 2.4
Var-Index: (2.4 ÷ 19.6) × 100 = 12.4% — ROCK SOLID
