    Okay, thanks for your help. What I have been doing is using the coefficant of correlation on the list of numbers and depending on the level of correlation I will use either the coefficient of determination or coefficant of variance to determine consistency. Thanks again for your help and have a great day.

    No, you’re absolutely right. My problem was that I’m looking for some metric that  shows the level of consistency if some historical trend line. I have been using CV and CD but CV by itself doesn’t look for a trend, just the consistency, while CD doesn’t seem to be able to measure a stable trend line. I wanted to know what would be the best metric to detect the consistency of a trend line, for example if I was trying to find the consistency of some species exponential growth or if I was looking at extraneous factors influencing the ratio from predators to prey in the region. I just wanted to sharpen up my current consistency  measuring strategies to something a bit more sophisticated.

    Thanks for answering, and I get what you’re saying. The things is that I am trying to predict if the future of a metric will behave similar to current affairs, and I wanted to use the consistency of some metric as the signal if it would. I was looking for some current affairs metric that can tell me if something like the historical average growth rate will continue or if a certain ratio will stay stable in the future. But if not what do you think is a better calculation to predict the future?
