Poll Horse Race Rounding Sum 100 Checker

Audit observed poll category total under explicit per-cell closed rounding intervals, not merely a table sum; feasibility assumes exhaustive disjoint categories and is conservative at half-open real rounding ties, not statistical validity or a corrected poll result.

Description

Rounded exhaustive disjoint poll categories may sum above or below 100.

Rounded exhaustive disjoint poll categories may sum above or below 100. Caller-supplied rounding intervals can test arithmetic feasibility.^[1]

Enter aligned nonempty percentages 0–100 and half widths0–50 points. Return published sum, possible-total interval and inclusive100-feasibility flag.

When to use Poll Horse Race Rounding Sum 100 Checker

Use Poll Horse Race Rounding Sum 100 Checker when you need to evaluate the supplied records under the calculation and evidence rules below. Closed intervals are conservative at actual half-open rounding ties. No statistical validity, exhaustive-category verification or corrected result is supplied.

Prepare the actual editorial, source, layout, timing or audience records requested. Supply explicit house-policy limits and preserve missing evidence.

How to use Poll Horse Race Rounding Sum 100 Checker and understand its results

Prepare the actual editorial, source, layout, timing or audience records requested. Supply explicit house-policy limits and preserve missing evidence.
Enter publishedPollPercentages, roundingHalfWidthsPercentagePoints using the field table and calculation rules, then run the tool.
Read publishedPercentageSum, possibleUnroundedTotalIntervalPercent, totalHundredFeasibleUnderCallerRounding. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
publishedPollPercentages	Published poll percentages	list of number	Required
roundingHalfWidthsPercentagePoints	Rounding half widths percentage points	list of number	Required

Enter aligned nonempty percentages 0–100 and half widths0–50 points. Return published sum, possible-total interval and inclusive100-feasibility flag.

lower=sum(max(0,p−halfWidth)); upper=sum(min(100,p+halfWidth))

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
publishedPercentageSum	Published percentage sum	number
possibleUnroundedTotalIntervalPercent	Possible unrounded total interval percent	list of number
totalHundredFeasibleUnderCallerRounding	Total hundred feasible under caller rounding	boolean

Limitations and assumptions

Closed intervals are conservative at actual half-open rounding ties. No statistical validity, exhaustive-category verification or corrected result is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Small Denominator Instability Warning Checker: A single numerator event changes a rate more when its denominator is small. This sensitivity is different from a confidence interval. For a complementary task, use Election Too Close to Call Margin Threshold Lookup: A two-candidate margin can be screened against a caller’s worst-case outstanding and error bounds. An interval crossing zero includes a possible tie.
