title: Why are Google Analytics Dashboard statistics changing?
body: <p>Background:</p>
  
  <p>I have a Google Analytics account using which I am tracking user activity for web and mobile app. After logging into your account and choosing the web property and the corresponding view, you generally see a dashboard with quick stats like Pageviews, Users, Sessions, Pages/Sessions, Avg. Session Duration, Bounce Rate and percentage of new sessions. You can change the time period (from the top right area of the Dashboard) to get the same stats for that period.</p>
  
  <p>Problem:</p>
  
  <p>Last week, I was interested in the three main stats: Page views, Users and Sessions for a particular day - say, day A. The dashboard showed the following stats:</p>
  
  <pre><code>Pageviews - 1,660,137
  Users - 496,068
  Sessions - 983,549
  </code></pre>
  
  <p>This report was based on 100% of sessions.</p>
  
  <p>I go back to the dashboard TODAY and check the same stats for the same day A. Here's what I saw:</p>
  
  <pre><code>Pageviews - 1,660,137
  Users - 511,071
  Sessions - 1,005,517
  </code></pre>
  
  <p>This report is also based on 100% of sessions.</p>
  
  <p>Nothing was changed in the tracking code for the web and mobile app. Could someone explain why I have this difference in the stats? Is this normal?</p>
