<p><strong><span style="color:#27ae60;">How Do We Calculate It (The Formula)</span></strong></p>
<p><span style="font-size:20px;">$$\frac{sum \ of \ all \ data}{\# \ of \ numbers}$$</span></p>
<p><strong><span style="color:#e74c3c;">Example</span></strong></p>
<p style="margin-left: 40px;"><em>What is the mean, or average, of the seven numbers below?</em></p>
<p>$$6, 5, 13, 8, 20, 14, 11$$</p>
<p style="margin-left: 40px;"><strong>Step 1</strong>: Calculate the sum of the seven numbers.</p>
<p>$$6+5+13+8+20+14+11 = 77$$</p>
<p style="margin-left: 40px;"><strong>Step 2</strong>: Divide the sum from step 1 by the number of numbers.</p>
<p>$$\frac{77}{11}$$</p>
<p><strong><span style="color:#27ae60;">$$=11$$</span></strong></p>
