You have duplicate records that must be removed from a data set in IBM SPSS Modeler Professional. The appropriate node to perform this action would be found in which palette tab?

Question

Options

• ASources
• BRecord Ops
• CField Ops
• DExport

• B
  92% (23)
• C
  4% (1)
• D
  4% (1)

Explanation

Record Ops (Record Operations) is the correct palette tab because removing duplicate records is an operation that acts on entire rows of data - the Distinct node, found in this tab, filters out duplicate records from a dataset. The Sources tab (A) is for bringing data into the stream, not manipulating it. Field Ops (C) handles column-level transformations like deriving or filtering fields, not rows. Export (D) is for writing data out to files or databases, not cleaning it.

Memory tip: Think of the distinction as rows vs. columns - "Record Ops" = row-level operations (duplicates are a row problem), "Field Ops" = column-level operations. If you're touching whole records, go to Record Ops.
