title: Standard error in psych::describe function - what is it referring to?
body: <p>Suppose we have a dataframe called "df", and we want to know the skewness and kurtosis values for a variable within df called "x".
  Suppose we use:</p>
  
  <pre><code>psych::describe(df$x)
  </code></pre>
  
  <p>And get the following result:</p>
  
  <pre><code>  vars n  mean  sd median  trimmed mad   min max range  skew  kurtosis  se
  1   1 478 98.54 19  102.5  100.57 18.53  34  125  91    -0.94   0.47    0.87
  </code></pre>
  
  <p>To what is the last value, the se, referring? The standard error of skew or kurtosis?</p>
