ITPEC FE Morning October 2019 — Question 53 of 80
Parametric Estimate — estimating durations by statistically analyzing past data and deriving coefficients.
Parametric estimating uses historical data and statistical relationships (coefficients) to calculate estimates. For example, if past data shows 1 line of code takes 0.5 hours, then 1,000 lines = 500 hours.
The key signal in this question is "statistically analyzed" and "coefficients" — these point directly to the parametric method.
Why not others:
- (a) Analogous estimate — uses a similar past project as a rough baseline; no statistical modeling or coefficients involved
- (b) Bottom-up estimate — decomposes work into small tasks, estimates each, then sums them up; no statistical analysis
- (d) Three-point estimate — uses three values (optimistic, most likely, pessimistic) with the PERT formula (O + 4M + P) / 6; probabilistic but not coefficient-based
Key rule: "Statistically analyzed past data + coefficients" = Parametric estimate.
