The procedure for analyzing the results of an in-store test is best captured by evaluating the change in sales from the base period to the test period for both groups. This method allows for a comprehensive understanding of the test's effectiveness by focusing on the difference in sales that occurred due to the test conditions. By comparing both the baseline figures and the test results, it provides insight into the impact of the test on sales performance.

This approach helps in establishing a clear picture of the test's results rather than just looking at raw sales totals or making comparisons without a thorough understanding of context. It highlights not only how the test store performed but also frames that performance against a defined baseline, ensuring that variations are attributable to the test itself rather than to general market fluctuations.

In contrast, focusing solely on sales totals during the test period negates the critical baseline context. Comparing test store sales to overall market sales may not accurately reflect the specific impact of the test unless the test store's unique conditions are taken into account. Finally, only assessing the control store would miss the opportunity to evaluate the effects of the alterations intended by the test, leading to potentially misleading conclusions. A comprehensive analysis accounts for the conditions before and during the test in both groups.
