Data Dredging
Suppose there is a given data set and there are a huge number of hypotheses [1] about this data set [2]. If the data is totally random, then say all the hypotheses are actually false. However, owing to the sheer number of hypotheses on a limited data set, it is possible to see some very highly correlated [3] data that are statistically significant [4]. In such cases, data dredging is said to ha...

متن کاملEffects of Dredging
BACKGROUND: Public laws regulating dredged material disposal (Section 404 of the Clean Water Act and Section 103 of the Ocean Dumping Act) require ecological evaluation prior to the permitting of operations. Assessment of the potential for bioaccumulation of chemical contaminants in sediment, including heavy metals, is required as part of the evaluation process. Metals can represent significant...
متن کاملEvaluating the effectiveness of contaminated-sediment dredging.
ater bodies fed by current or former industrial, agricultural, or mining areas frequently contain contaminated sediments, and throughout the U.S., miles of riverbeds and vast areas of harbors, lakes, and estuaries are affected (1, 2). Contaminants in sediments can have direct toxic effects on organisms and can accumulate in organisms consumed by humans. The presence of sediment contamination al...
