# 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?

Yes.I reference the following standard in my community -- "Median Trend Chart and Interpretation" https://wp.me/p7eYCh-5k This is a method advocate in healthcare.

I'm not a statistician -- it would be nice to have a recommendation for the media. I always liked the AIAG interpretation standard of 7 points -- ASQ/PQ used in support of Koalty Kid (K-12). E.G., 7 data points in a row above or below the average, 7 data points in a row trending up or down. This is the easiest to remember. Mike Cleary explained the significance of the 7 data points that made sense to me. My interpretation -- If you flip a coin and get 7 consecutive heads or tails, it's possible but not "usual." I think it's generally accepted that the XMR is a good all-purpose control chart. But, just introducing the fact that there are accepted and proven standards for interpreting a trend would be a significant improvement. Can we keep it simple?
