Data Quality Analysis and Management

Results of the field sampling program, including information recorded on field datasheets and laboratory results should be reviewed by the (field) team leader and reviewed for potential errors/omissions and to identify anomalous results. Results are then entered into Excel spreadsheets (if not already in that form) and checked for transcription errors. Original raw data files (including field notes) must be retained; and duplicate files should be used for data analysis and manipulation.

A log of statistical analyses performed and hard copy of output should be retained in the project file, so that analyses can be reviewed and reproduced if needed. All project-related documents, including datasheets, field notes, photographs, maps and other supporting documentation should be filed in a secure and well organized location. Key data should be stored in a fireproof filing cabinet.
