Define your data cleaning scenario clearly

Vague prompts yield unclear results. Specify details like data type (e.g., “customer transaction records” or “sensor readings”), cleaning objectives (e.g., “remove duplicates” or “normalize date formats”), or dataset size (e.g., “large-scale logs from IoT devices”).

Example: “Identify and correct inconsistent date entries in sales data from 2023.”

Use comparative prompts to evaluate methods

AI excels at contrasting approaches. Use prompts like “compare method A vs method B” to assess cleaning techniques, error detection algorithms, or preprocessing pipelines.

Example: “Compare the effectiveness of outlier detection using Z-score versus IQR on financial data.”

Frame prompts around specific data tasks

Treat your prompt as a precise instruction for AI. Instead of generic requests, focus on the task:

Example: “Generate a step-by-step plan to handle missing values in a customer demographics dataset prioritizing accuracy.”

Specify desired output formats

Need a checklist, code snippet, or summary report? Clearly state the format. AI delivers better when output expectations are set.

Example: “Provide a bullet list of five key preprocessing steps for time-series sensor data with brief explanations.”
