title: How is uniformity expressed?
body: <p><em>I don't know anything about statistics and it was difficult for me to find A way to describe my question that was clear.</em></p>
  
  <p>I am doing some initial research on a system that will measure the uniformity of electricity across a conductor.  Basically we need to measure how evenly a signal is spread out on a surface.</p>
  
  <p>I was doing research on how to determine uniformity of a data set and came across <a href="https://stackoverflow.com/questions/4259463/quick-way-to-calculate-uniformity-or-discrepancy-of-number-set">this question</a> which is promising.  However I realized that I don't know what unit to use to express uniformity.  For example, if I take 100 equally spaced measurements in a grid pattern on the surface of an object and want to describe how uniform the values are, how would you say it?</p>
  
  <ul>
  <li>"98% uniform?" - what does that mean? 98% of what?</li>
  <li>"The signal is very evenly dispersed" - OK, great... but there must be a more specific or scientific way to communicate that... how "evenly"?  What is a numeric representation of that statement?</li>
  </ul>
  
  <p>Statistics and math are not my thing so if this seems like a dumb question, be gentle...</p>
