Question 7 NECO • 2022 • DATA_PROCESSING • objective

In a typical data processing cycle, the stages are: (1) data collection, (2) data storage, (3) data processing, (4) data analysis, and (5) presentation. A company collects sales data daily, stores it in a database, then runs a program that cleans the data before generating monthly reports. However, errors are still appearing in the reports because some invalid entries are not being detected. At which stage of the data processing cycle should data validation be performed to prevent these errors, and why?

Answer Options

A. During the storage stage, because validating data when it is saved prevents corrupted records from being processed later.
B. During the analysis stage, because verifying data just before interpretation catches any remaining issues before presentation.
C. During the collection stage, because checking data as it is gathered ensures errors are caught before storage.
Correct Answer D. During the processing stage (data cleaning), because validation at this point removes erroneous entries before analysis and presentation.
Correct Answer
D
Correct Option:
During the processing stage (data cleaning), because validation at this point removes erroneous entries before analysis and presentation.
