IBM SPSS Statistics Level 1 v2 — Question 9

Which partitioning method requires a key?

Answer options

• A. Entire
• B. Same
• C. Range
• D. Random

Correct answer: B

Explanation

The 'Same' partitioning method requires a key to ensure that data is distributed across partitions based on that key. In contrast, the 'Entire' method does not rely on a key and partitions the entire dataset, while 'Range' and 'Random' methods use different criteria for partitioning, not specifically a key.
