May 24 2013 Missing data or missing values is defined as the data value that is not stored for a variable in the observation of interest The problem of missing data is relatively common in almost all research and can have a significant effect on the conclusions that can be drawn from the data Accordingly some studies have focused on handling the missing data problems caused by Dec 10 2020 Mining coal Coal miners use large machines to remove coal from the earth Many US coal deposits called coal beds or seams are near the earths surface while others are deep undergroundModern mining methods allow coal miners to easily reach most of the nations coal reserves and to produce about three times more coal in one hour than in 1978
