Experimental Design

Field review: the conversation in which a scope, a constraint or a decision is actually settled.

Experimental and Laboratory Design Studio

Design an experiment that can be repeated: variables, specimens, replicates, controls and analysis plan.

Design an experiment that can be repeated: variables, specimens, replicates, controls and analysis plan.

Learning objectives

  • Distinguish independent, dependent and controlled variables
  • Size specimen groups and controls
  • Plan the statistical analysis before testing

Engineering guidance

Specimen quantity, curing age and control group must be stated before the first batch is cast.

FE Civil connection

Materials

Handbook §11 — Material testing (placeholder)

  • How many replicates support a mean strength claim?
  • Which standard governs a compressive strength test?
  • What invalidates a test result?

Technical methodology planner

Plan Chapter 3 against the exact equations, standards, data sources and design checks you will execute in Capstone II.
