Statistical.μ(freq) ⇒
Calculate arithmetic mean of ball-count
Kind: static method of Returns: — Arithmatic Mean of weights
| Param | Type | Description |
|---|---|---|
| freq | A single ball-frequency array from |
Example (Get Arithmetic Mean of Red Balls)
var f = powerball.frequencies(winners)
console.log(powerball.μ(f.red))
Example (Get Arithmetic Mean of White Balls)
console.log(powerball.mean(f.white))
Statistical.gmean(freq) ⇒
Calculate geometric mean of ball-count
Kind: static method of Returns: — Geometric Mean of weights
| Param | Type | Description |
|---|---|---|
| freq | A single ball-frequency array from |
Example (Get Geometric Mean of Red Balls)
var f = powerball.frequencies(winners)
console.log(powerball.gmean(f.red))
Example (Get Geometric Mean of White Balls)
console.log(powerball.gmean(f.white))
Statistical.median(freq) ⇒
Calculate median of ball-count
Kind: static method of Returns: — Median of weights
| Param | Type | Description |
|---|---|---|
| freq | A single ball-frequency array from |
Example (Get Median of Red Balls)
var f = powerball.frequencies(winners)
console.log(powerball.median(f.red))
Example (Get Median of White Balls)

Statistical.range(freq) ⇒
Calculate range of ball-count
Kind: static method of Returns: — High/low range of numbers for weights.
| Param | Type | Description |
|---|---|---|
| freq | A single ball-frequency array from |
Example (Get Range of Red Balls)
var f = powerball.frequencies(winners)
console.log(powerball.range(f.red))
Example (Get Range of White Balls)
console.log(powerball.range(f.white))
Statistical.σ(freq) ⇒
Calculate standard deviation of ball-count
Kind: static method of Returns: — Standard Deviation of weights
| Param | Type | Description |
|---|---|---|
| freq | A single ball-frequency array from |
Example (Get Standard Deviation of Red Balls)
var f = powerball.frequencies(winners)
console.log(powerball.stddev(f.red))
Example (Get Standard Deviation of White Balls)
console.log(powerball.σ(f.white))
