<p>&lt;h2&gt;Notes&lt;/h2&gt; &lt;ul&gt; &lt;ul&gt; &lt;li&gt; &lt;p&gt;&lt;strong&gt;Independent Variable&lt;/strong&gt;: the variable you&amp;nbsp;&lt;strong&gt;manipulate&lt;/strong&gt;&amp;nbsp;(&amp;ldquo;type of hair&amp;rdquo; in this example).&lt;/p&gt; &lt;/li&gt; &lt;li&gt; &lt;p&gt;&lt;strong&gt;Dependent Variable&lt;/strong&gt;: the variable you&amp;nbsp;&lt;strong&gt;measure&lt;/strong&gt;&amp;nbsp;(&amp;ldquo;credibility&amp;rdquo; in this example).&lt;/p&gt; &lt;/li&gt; &lt;li&gt; &lt;p&gt;&lt;strong&gt;Operational Definition&lt;/strong&gt;: the exact&amp;nbsp;&lt;strong&gt;data&lt;/strong&gt;&amp;nbsp;that you will collect.
