## Revising Data TogetherAcross EIA 

**Renee Miller and Alethea Jennings**
**Statistics and Methods Group, EIA**
**April 23, 2004**

## Why Revise Together?

**More data dependencies**
**Web enables users to easily obtain data from different publications and notice if they don’t match**

## Outline

**Current revision standard**
**Discussions on coordinating revisions**
**An opportunity for inter-office coordination on revising “final” data**
**Next steps**
**An example of a revision trail**
**Showing the “latest/greatest” on the Web**

## Current Revision Standard

**No more than two revisions of same survey data cell**
**Allows for unscheduled revisions to correct previously unrecognized errors**
**Does not address modifications to “final” data**

## Discussions on Revisions

**Scheduling revisions**
**Limiting the number of revisions**
**An opportunity for revising together to address modifications to “final” data**

## Revising Together  Through Inter-office Coordination

**               **
**                **

**Data revision decisions no longer made in isolation**
**Other offices must be notified and agree on pending change**
**When there is disagreement, the Inter-office Issues Group will discuss concerns**

## Next Steps

**Issue policy on revising “final” data**
**Update revision standard**
**Address other issues pertaining to revisions before data become “final”**

## An Example of a Revision Trail

**Data on natural gas delivered to the residential sector**
**Reporting period:  January 2002**
**Publication period:  April 2002 – January 2004**

## Latest/Greatest-Advantages

**Errors would be corrected**
**Users would have the latest data, so EIA would not have to scramble to produce it when it was requested**

## Latest/Greatest-Disadvantages

**Maintaining the site could be an added burden to EIA staff**
**Different vintages of data could cause confusion for users**
**The latest may not actually be the greatest  **

## Questions for the Committee

**When EIA developed its revision standard in the early eighties, we were trying to establish our credibility and thought that limiting the number of revisions was a good thing.  Is this still a good assumption?**
**Regarding the natural gas data for the residential sector, does the committee have suggestions for another approach for presenting revisions?**

## 
Would it ever be an acceptable practice to publish data where the components do not sum to the total?

What does the committee think about showing  “the latest/greatest” on the Web?
