The Missing Values tab of the Variable Update window is used to define missing values for numeric variable types.  Missing values are used so as to not leave a field blank during data entry and still be able to distinguish it during analysis as not real data.

Content

• Begin Value: The beginning value for the missing value

  Tip
  The missing value can be outside the range of the Minimum and Maximum specified on the Attributes tab for the variable

• End Value:  The end value for the missing value

  Info
  The End Value can be the same as the Begin Value

• Name:  The name for the missing value (e.g., Unknown, Refused, Unable to obtain result)
