Poor Data ManagementAffects Everyone “MEDICARE PAYMENT ERRORS NEAR $20B” | (CNN) December 2004 Miscoding and billing errors from doctors and hospitals totaled $20,000,000,000 in FY2003 (9.3% error rate). The error rate measured claims that were paid despite being medically unnecessary, inadequately documented or improperly coded. In some instances, Medicare asked health care providers for medical records to back up their claims and got no response. The survey did not document instances of alleged fraud. This error rate actually was an improvement over the previous fiscal year (9.8% error rate). “AUDIT: JUSTICE STATS ON ANTI-TERROR CASES FLAWED” | (AP) February 2007 The Justice Department Inspector General found only two sets of data out of 26 concerning terrorism attacks were accurate. The Justice Department uses these statistics to argue for their budget. The Inspector General said the data “appear to be the result of decentralized and haphazard methods of collections … and do not appear to be intentional.” “OOPS! TECH ERROR WIPES OUT ALASKA INFO” | (AP) March 2007 A technician managed to delete the data and backup for the $38 billion Alaska oil revenue fund – money received by residents of the State. Correcting the errors cost the State an additional $220,700 (which of course was taken off the receipts to Alaska residents.) Slide courtesy of BLM

When the biologist relocated to another office, no one understood how the data was stored or managed. Solution: A state office GIS specialist retrieved the workstation and sifted through files trying to salvage relevant data. Cost: 1 work month ($4,000) plus the value of data that was not recovered Poor Science Data Management Example CCimagebyDTRaveon OpenClipArtLibrary

Lafrenière et al., Astrophysical Journal Letters “The first thing it tells you is how valuable maintaining long-term archives can be. Here is a major discovery that’s been lurking in the data for about 10 years!” comments Matt Mountain, director of the Space Telescope Science Institute in Baltimore, which operates Hubble. “The second thing its tells you is having a well calibrated archive is necessary but not sufficient to make breakthroughs — it also takes a very innovative group of people to develop very smart extraction routines that can get rid of all the artifacts to reveal the planet hidden under all that telescope and detector structure.” “Planet hidden in Hubble archives” Science News Feb. 27, 2009 D.Lafrenièreetal.,ApJLetters
- 29. The data delugehas created a surge of information that needs to be well-managed and made accessible. The cost of not doing data management can be very high. Be cognizant of best practices and tools associated with the data lifecycle to manage your data well. Many benefits are associated with the act of managing data, including the ability to find, access, understand, integrate and re-use data. Summary

- #9 Does not include, “any of the following: preliminary analyses, drafts of scientific papers, plans for future research, peer reviews, or communications with colleagues. This "recorded" material excludes physical objects (e.g., laboratory samples).” This narrow definition mostly takes a retrospective view of your dataset, in that it does not account for raw and intermediate data that may be critical to the research process but that don’t become part of the ’final’ dataset. Data types could be: Observational Experimental Simulated Derived Reference or canonical
- #10 …”Data may be viewed as the lowest level of abstraction from which information and knowledge are derived.”
- #11 Data management is a verb – it involves intentional effort and activity. The main goals of DM are preservation and reuse, for you and for others. Covers all aspects of the data lifecycle from planning digital data capture methods, whittling down, ingestion to databases, providing for access and reuse, to transformation.
- #12 If this is why you are here, you signed up for the wrong class.
- #14 Let’s look at one important area of scientific inquiry: climate change. What scale of data integration is necessary to study global trends over geologic timescales?
- #15 Data are being generated in massive quantities daily. Improvements in technology enable higher precision and coverage in data acquisition and makes higher capacity systems store and migrate more data –increasing the importance of managing, integrating, and re-using data. In order to integrate these diverse datasets to answer questions of global significance, the data have to be well organized, well documented and described, preserved and accessible. It all depends of effective management of the data. Slide credit: DataONE Education Module 1.
- #16 The amount of available storage is not keeping up with the amount of data flooding in daily. How do we decide what data we keep? Slide credit: DataONE Education Module 1.

- #18 Data Costs Consider some of the data management issues that made headlines, affecting agencies and organizations. Data quality is not limited to any one organization. These examples show costs (in terms of money lost) due to a lack of data quality control. Slide credit: DataONE Education Module 1.
- #19 Consider this situation in an academic context. How common do you think it is that data are lost when graduate students leave, because their adviser either can’t find the data, doesn’t understand the file names or how the data are organized, or because the data aren’t documented well enough (e.g. experimental or observational conditions, human subject codes, samples vs. controls, etc.)?

- #20 After investigations by the House of Commons Science and Technology Committee (UK), Inspector General of the U.S. Department of Commerce, the National Science Foundation, the National Research Council of the National Academy of Sciences, and Pennsylvania State University, no evidence of scientific misconduct or wrongdoing was discovered. The scientists were able to show all of their data, software codes and other research materials to put the hacked emails into the context of rigorous discourse among colleagues. If they hadn’t been able to provide all of the evidence to support their conclusions on climate change, “Climategate” would likely still be going on.

- #21 “How long should I retain data?” is not a clear and cut data management question. Last year, for example, the JCI retracted a published article because one of its data tables was duplicated. The publisher contacted the researchers to have them update the data, but they could not locate the original data files after six years, so the journal was forced to issue a retraction.

- #22 Manage your data for yourself: Keep yourself organized – be able to find your files (data inputs, analytic scripts, outputs at various stages of the analytic process, etc.) Track your science processes for reproducibility – be able to match up your outputs with exact inputs and transformations that produced them Better control versions of data – identify easily versions that can be periodically purged Quality control your data more efficiently Slide credit: DataONE Education Module 1.

- #24 Data should be managed to: maximize the effective use and value of data and information assets continually improve the quality including: data accuracy, integrity, integration, timeliness of data capture and presentation, relevance and usefulness ensure appropriate use of data and information facilitate data sharing ensure sustainability and accessibility in long term for re-use in science Slide credit: DataONE Education Module 1.
- #25 By re-using data collected from a variety of sources – eBird database, land cover data, meteorology, and remotely sensed -- this project was able to compile and process the data using supercomputering to determine bird migration routes for particular species.
