“The Statistical Testing Tool is a spreadsheet that tests whether American Community Survey (ACS) estimates are statistically different from one another. Simply copy or download ACS estimates and their margins of error (MOE) into the tool to get instant results of statistical tests.
Tool Features:

• Compares up to 3,230 pairs of estimates at once
• Compares multiple estimates simultaneously (up to 150 estimates)
• Displays statistical testing results (“Yes”, “No”) automatically
• Handles special formatting and characters, such as the ‘+/-‘ in front of the MOE, without additional editing by the data user
• Uses the Census Bureau’s standard 90% confidence level, but can also process statistical testing at 95% or 99% confidence levels
• May be used to conduct statistical testing for other Census Bureau surveys”
