Which estimating technique uses the actual costs of previous similar projects as a basis for estimating the costs of the current project?
The correct answer is A. Analogous. Analogous estimating (A) is correct because it explicitly uses historical data from similar past projects to estimate current project costs - the word "analogous" means "similar," making this a direct match to the technique's definition.

Explanation
Analogous estimating (A) is correct because it explicitly uses historical data from similar past projects to estimate current project costs - the word "analogous" means "similar," making this a direct match to the technique's definition.
Parametric (B) uses statistical relationships between variables (e.g., cost per unit × quantity), not direct historical project comparisons. Bottom-up (C) builds estimates from detailed individual work components and rolls them up - no reliance on past projects. Top-down (D) is not a standard PMI estimating technique name; it describes a direction of decomposition, not a cost estimation method.
Memory tip: Think "analogous = analogy" - you're drawing an analogy to a previous project, just as you'd compare a new house build to a similar one you built before.
