title: How to calculate Weighted Frequency
body: <p>I am doing a school project on a dataset. I can not understand one of the specific column of the dataset.</p>
  <p>Data is as follows. This is an instance of whole dataset</p>
  <p>Question: Define your gender?</p>
  <p>Responses</p>
  <pre><code>                             Unweighted Frequency                Weighted Frequency
  
        Female                 887                                  49.9                             
  
        Male                   865                                  50.1
  
        Missing                15
  </code></pre>
  <p>Definition:</p>
  <p>Unweighted Frequency: This column contains the number of people who chose a specific response
  option or response of interest.</p>
  <p>Weighted Frequency: This column contains the percentage of people who chose a specific
  response option or response of interest. These percentages are weighted and
  represent people of a country</p>
  <p>Now, I can not understand how could I find out Weighted Frequency.</p>
  <p>I mean if I apply the method: (887+865+15) = 1767</p>
  <p>Female: (887/1767) = 0.50198   which is not equal to 49.9 even if I multiply it with 100.</p>
  <p>Any help would be appreciated.</p>
