title: Pearson correlation coefficient 2-tailed p-value meaning
body: <p>from the sciPy library I used: scipy.stats.stats import pearsonr to calculate the correlation coefficient for two arrays and I got a value of: (0.80751532276005755, 0.19248467723994242). </p>
  
  <p>I thought that I would have just got one value within the range -1 to +1, so I'm unsure how to interpret these two results. These are my two arrays:</p>
  
  <pre><code>x = [50,500,1500,2500]
  y = [17, 6, 6, 194]
  </code></pre>
  
  <p>and I did:</p>
  
  <pre><code>pearsonr(x,y)
  </code></pre>
  
  <p>Thanks</p>
