• value neglected

• value is ignored

• value replaced by other value

redundancy problem can be solved by

• standard deviation

• median

• correlation analysis

• regression

converting attribute into same measurement is

• preprocessing

• discretization

• normalization

• nominal conversion

Missing data may not be due to

• inconsistent with other recorded data and thus deleted

• certain data may not be considered important at the time of entry

• equipment well function

• •not register history or changes of the data

... is Smoothing technique

• Classification

• Binning

• Regresion

• Clustering

.. is not handling missing data

• Ignore the tuples

• Fill in the missing values manually

• Fill in the missing values automatically

• Deleting the missing values
