IBM SPSS Statistics Level 1 v2 — Question 14

Which of the following is NOT a valid use of stage variables?

Answer options

• A. Storing values to be used in both derivations and constraints
• B. Storing values that can be referenced by name in downstream stages
• C. Storing values from one row to compare with values in the next row read
• D. Storing the result on an expression to be used in multiple output columns

Correct answer: D

Explanation

Option D is correct because stage variables cannot be used to store an expression's result for multiple output columns; they are typically used for intermediate calculations within the same stage. Options A, B, and C are valid uses of stage variables as they involve storing and referencing values for various purposes in the data flow.
