title: Haskell. Assigning name to a threshold of values
body: <p>I'm trying to figure out how to write in Haskell:</p>
  
  <p>There is a list made of 4 variables: [w,x,y,z]
  After completing the following through ghci:</p>
  
  <pre><code>collection :: Int -&gt; Int -&gt; Int -&gt; Int -&gt; [Int]
  collection w x y z = [w,x,y,z]
  </code></pre>
  
  <p>I want to assign a "meaning" to each threshold value for w,x,y,z. Example: when 0 &lt; x &lt; 60, then x = "Low", when 59 &lt; x &lt; 80, then x = "Medium", when 79 &lt; x &lt; 100, then x = "High"</p>
  
  <p>How do you put that in Haskell code?</p>
