is the only value between 3 and 3. If the 17th value happened to be 4, then we would have determined the median as the value halfway between 3 and 4, i.e. as 3.5.</p>
<p>The <strong>mode</strong> is the most frequently occurring value. This measure is really only useful for relatively large data sets with a limited number of possible values. For a continuous variable, there is generally no value that occurs more than once in a data set, and hence all values could be considered a mode. If we look at the tot
