Template:ConfidenceInterval

Usage

Calculates the 95% confidence interval for inputs k successes on n total number of draws. Returns a percentage value without % sign with two digits (if more or less digits are desired, use the digits argument).

{{ConfidenceInterval|k|n}}

• 50 success on 100 draws represents a success rate of (50 +/- 9.8)%
• 250 success on 500 draws represents a success rate of (50 +/- 4.38)%
• 50 success on 500 draws represents a success rate of (10 +/- 2.62962)% (displaying up to 5 digits with the digits argument here).
• 100 success on 100 draws represents a success rate of (100 - 3)%
• 0 success on 100 draws represents a success rate of (0 + 3)%
• 4765 success on 4765 draws represents a success rate of (100 - 0.06)%
• 0 success on 365 draws represents a success rate of (0 + 0.82)%
• 100 success on 10 draws represents a success rate of (1000 )% (this is a case where the confidence interval makes no sense, thus it is not reported if k > n).
