3. Time Series Analysis: Analyze data over time to identify trends that inform forecasting.
4. Quality Control: Apply statistical quality control methods to maintain or improve product quality.

The choice of analysis depends on the objectives of the business and the nature of the data collected.

2. Transparent Methods: Using statistical methods that are transparent and can be verified by others.
3. Honest Reporting: Presenting data and findings honestly, without manipulation.
4. Compliance with Regulations: Adhering to industry regulations and standards for data use.

By following these ethical guidelines, businesses maintain integrity and trust in their statistical practices.
