Suggestions - National Trend Interpretation Standard (s)?
Whether it suicide rates, crime, or GDP, the national media (and most everyone else) concludes significance by comparing two data points. To introduce the fact that there are generally accepted trend interpretation standards, should the quality community advocate for the application of one or more standard (s)? A trend chart would be a "gateway" to control charts (trend charts with control limits). If yes, is there one or more standards that you would recommend? If we had a link to the standards, we could reference the link when responding to misleading headlines. Thoughts?
