In an in-store test process, performing comparisons at the end of periods is a practice retailers should avoid because it can lead to misleading conclusions about the effectiveness of the test variables. When comparisons are made only after the testing period is complete, it limits the ability to analyze trends over time and assess the impact of changes in a dynamic environment. Retailers need to capture data throughout the entire testing phase to see how consumer behavior might change and to gather meaningful insights.

By conducting comparisons only at the conclusion of a period, important variations and consumer reactions that occur during the testing process may be overlooked. Continuous analysis helps ensure that decisions are based on comprehensive data that reflects the test's performance, making it easier to derive actionable insights.

In contrast, allowing sufficient testing time, calculating pre-test changes, and using control stores appropriately are all practices that support a thorough and effective evaluation of the test's impact, leading to more reliable results and informed decisions.
