Parametric Estimating

Technique using an algorithm or statistical relationship between historical data and variables to calculate estimates.

Definition

Accuracy depends on the sophistication of the model and quality of data. It scales a unit rate by quantity.

Example

At 20 hours per 1,000 lines of code, 15,000 lines will take 300 hours.

Exam tip

Look for a unit rate multiplied by quantity: that's parametric.
