The systematic assignment of numbers or letters to items to classify and organize them is called what?

• A. Coding
• B. Deviation
• C. Continuous scale/variable
• D. Discrete variable

Answer: (A)

Assigning numbers or letters to items to classify and organize them is coding. This process creates a consistent mapping from categories to codes, which makes data entry, storage, and analysis straightforward and reliable. Coding is about labeling and grouping items so they can be easily counted and compared across cases. This isn’t the same as a measurement approach like a continuous scale or discrete variable, which describe how data values are measured rather than how categories are labeled. It also isn’t about deviation, which refers to how far a value is from a reference point. So coding best fits the description of systematically labeling items for organization and analysis.
