Experimental design and comparison

Design conditions and comparisons to examine how a changed factor relates to observed outcomes.

Method · Marketing

Core concepts

• Factors and responses: define changes and measured outcomes
• Control: reduce the influence of alternative causes
• Replication and randomization: address variation and bias

Application

Before testing advertising, messaging or product changes, define metrics, the target population and stopping conditions.

Limitations and jurisdiction

Small samples, simultaneous changes and repeated interim decisions complicate interpretation. Statistical differences are not the same as business value.

Editorial perspectives

• Stronger control: improve the clarity of causal inference.
• Field relevance: retain operating conditions and examine external validity.
