Question details
The user needs to generate descriptive statistics for geographic coordinates (latitude and longitude) using the Data Analysis ToolPak.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Calculating statistical distributions and counts for coordinate data organized in columns.
- Observed behavior
- The Descriptive Statistics tool treats latitude and longitude as standard numerical values, generating separate univariate statistics. It counts numeric values and ignores empty cells, but produces misleading arithmetic averages for coordinates near the poles or the International Date Line.
Ensure the Analysis ToolPak add-in is enabled in your software and format your latitude and longitude data into two separate numeric columns with clear text labels in the first row.
Generate Descriptive Statistics for Coordinate Data
Use the Descriptive Statistics feature to calculate basic univariate statistics for geographic data columns.
The Data Analysis tool processes latitude and longitude exactly like standard numerical data. Empty cells are automatically ignored in the final count, providing the exact same result as using the COUNT function.
Place your latitude and longitude data in separate numeric columns. Ensure the very first row contains text labels (e.g., 'Latitude' and 'Longitude').
Navigate to the Data tab on your ribbon and click on 'Data Analysis' in the Analysis group.
Choose 'Descriptive Statistics' from the list of analysis tools and click OK.
Select the Input Range containing your data and headers. Check the box for 'Labels in first row', define your Output Range, check 'Summary statistics', and click OK to generate the report.

Frequently Asked Questions
Why is the average longitude incorrect for locations near the International Date Line?
Standard arithmetic averages do not account for the circular nature of the globe. Averaging +179 and -179 yields 0, placing the calculated center on the Prime Meridian rather than the Pacific Ocean. You must use circular statistics for accurate geographic calculations.
Does the Descriptive Statistics tool count empty rows in my data?
No, empty cells within your selected input range are ignored. The count statistic returned by the tool functions exactly like the standard COUNT function, so a range with 49 data rows and one empty row produces a count of 49.
Why do I get an error when running Descriptive Statistics on my columns?
This usually occurs if your selected data range includes text headers, but you forgot to enable the 'Labels in first row' option in the tool's dialog box. Ensuring this box is checked will resolve the error.
How do I add the Data Analysis tool if it's missing from my ribbon?
Go to File > Options > Add-ins. In the Manage box at the bottom, select Excel Add-ins and click Go. Check the box for Analysis ToolPak and click OK to enable the feature on your Data tab.
