Batting Consistency Calculator

What does this calculator mean?

Two batters can share the same average but play very differently: one scores steadily, the other swings between big hundreds and ducks. The batting consistency calculator uses standard deviation to show which is which.

A lower standard deviation means scores cluster closely around the average — a sign of a dependable batter.

How to use the batting consistency calculator

  1. Enter scores.
  2. Press Calculate consistency.
  3. Read the result below the button. Change any value and recalculate as often as you like.

Formula used

Consistency = Standard deviation of scores
SD = √( Σ(score − average)² ÷ number of scores )
Uses population standard deviation. The coefficient of variation (SD ÷ average) is also shown to compare players with different averages.

Example

For scores 50, 45, 60, 55: average = 52.5, SD ≈ 5.59 — very consistent scoring.

Frequently asked questions

Why use standard deviation?

It measures how spread out the scores are. A small spread means the batter delivers similar returns innings after innings.

How many scores should I enter?

At least two are needed, but ten or more recent innings give a more meaningful picture.
