<p>Two primary categories of experimental error:</p>
<ul>
<li>Systematic errors: consistent and repeatable biases in measurements. Systematic errors affect the accuracy of a measurement (how close it is to the true value).</li>
<li>Random Errors: unpredictable fluctuations in measurements. They can cause the measured values to be sometimes higher and sometimes lower than the true value, with no discernible pattern.</li>
