Use this calculation to reproduce a defined quantitative method when the observations, units, sampling process, and assumptions match the method shown here.

Values

Required list.

The cited overview of Statistics supplies background for the terminology and domain context used by this tool.^[1]

Count values outside the Tukey fences of one and a half interquartile ranges. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Outlier count

Returned integer.

• A numerical result does not by itself establish data quality, causation, representativeness, independence, distributional fit, or practical significance.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Inspect the underlying data, visualize its distribution, report uncertainty and sample size, and compare the result with a robust or domain-specific method where appropriate.

• Interquartile Mean Calculator

  Calculate the mean of the values between the inclusive first and third quartiles, ignoring outside extremes.

• Count Above Threshold Tool

  Count how many values in a list are strictly greater than a threshold.

• Frequency Table Generator

  Count numeric values and return a deterministic ascending frequency table.
