<p><a href="https://www.prepswift.com/quizzes/quiz/prepswift-mode" target="_blank">Mode Exercise</a></p><p>The <strong><span style="color:#8e44ad;">Mode</span></strong> is pretty straightforward. It's the data element that appears most often in the dataset.</p>
<p><strong><span style="color:#e74c3c;">Example</span></strong></p>
<p style="margin-left: 40px;"><em>What is the mode of the dataset below?</em></p>
<p>$$4, 7, 7, 3, 5, 4, 10, 7, 4, 4$$</p>
<p style="margin-left: 40px;">The number $4$ appears four times. No other number appears that often, so $4$ is the mode.</p>
<p><strong><span style="color:#27ae60;">Can There Be More Than One Mode?</span></strong></p>
<p style="margin-left: 40px;">Yep! Look at the <u>slightly</u> altered dataset below? What's the mode now? </p>
<p>$$4, 7, 7, 3, 5, 4, 10, 7, 4, 1$$</p>
<p style="margin-left: 40px;">Note that the numbers $4$ and $7$ both appear three times. So this is a <u><strong>bimodal</strong></u> (two modes) dataset. $4$ and $7$ are BOTH the mode. Mindblonw. It's also possible to have three modes, or four, or five...etc.</p>
<p><strong><span style="color:#e74c3c;">Well That Begs the Question...</span></strong></p>
<p style="margin-left: 40px;">If a dataset consists entirely of distinct numbers, do we say that it has no mode or do we say every number is the mode? It's one of life's mysteries.</p>
