    I store 3-4 months worth of accuracy values in a table. I would like to be
    able to display the information as a rolling average, which I can, but also
    show the trend. Any ideas would be appreciatted as at the moment I am stumped.

    Dear Rob:

    As far as I know, the term "trend" is not a specific mathematical or
    business term that would indicate exactly what you want. Is it a
    difference, a difference expressed as a percent change, or what? If based
    on a difference, is it a difference between successive values, or from a
    baseline?

    Please explain, give some source data, and the results that should be
    produced. Perhaps then someone can offer you some assistance.

    Tom Ellison

    I'm sure I will have lots of questions but this should keep me busy for most
    of the day...thank you very much!

    Tom what I am trying to do is show the user if their accuracy is increasing
    or decreasing over time without having to show them all the results of each
    month.

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
