<h1 class="center">Stem and Leaf Plots</h1>
|
|
|
|
<p>A <b>Stem and Leaf Plot</b> is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit). Like in this example:</p>
|
|
<div class="example">
|
|
<h3>Example:</h3>
|
|
<p class="center larger">"32" is split into "3" (stem) and "2" (leaf).</p>
|
|
<p class="center"><img src="images/stem-leaf-plot.svg" alt="Stem and Leaf Plot"></p>
|
|
<p>More Examples:</p>
|
|
<ul>
|
|
<li>Stem "1" Leaf "5" means <b>15</b></li>
|
|
<li>Stem "1" Leaf "6" means <b>16</b></li>
|
|
<li>Stem "2" Leaf "1" means <b>21</b></li>
|
|
<li>etc</li>
|
|
</ul>
|
|
</div>
|
|
<p>The "stem" values are listed down, and the "leaf" values go right (or left) from the stem values.</p>
|
|
<p>The "stem" is used to group the scores and each "leaf" shows the individual scores within each group.</p>
|
|
<div class="example">
|
|
<h3>Example: Long Jump</h3>
|
|
<p>Sam got his friends to do a long jump and got these results:</p>
|
|
<p style="float:right; margin: 0 0 5px 10px;"><img src="images/long-jump.jpg" alt="long jump" height="114" width="150"></p>
|
|
<p class="center"><b> 2.3, 2.5, 2.5, 2.7, 2.8 3.2, 3.6, 3.6, 4.5, 5.0</b></p>
|
|
<p>And here is the stem-and-leaf plot:</p>
|
|
<table align="center" cellspacing="0" cellpadding="4" border="1">
|
|
<tbody>
|
|
<tr>
|
|
<td style="text-align:center;">Stem</td>
|
|
<td>Leaf</td>
|
|
</tr>
|
|
<tr>
|
|
<td style="text-align:center;">2</td>
|
|
<td> 3 5 5 7 8</td>
|
|
</tr>
|
|
<tr>
|
|
<td style="text-align:center;">3</td>
|
|
<td>2 6 6</td>
|
|
</tr>
|
|
<tr>
|
|
<td style="text-align:center;">4</td>
|
|
<td>5</td>
|
|
</tr>
|
|
<tr>
|
|
<td style="text-align:center;">5</td>
|
|
<td>0</td>
|
|
</tr>
|
|
</tbody></table>
|
|
<p class="center">Stem "2" Leaf "3" means <b>2.3</b></p>
|
|
<p>Note:</p>
|
|
<ul>
|
|
<li>Say what the stem and leaf mean (<span class="center">Stem "2" Leaf "3" means <b>2.3</b></span>)</li>
|
|
<li>In this case each leaf is a decimal</li>
|
|
<li>It is OK to repeat a leaf value</li>
|
|
<li>5.0 has a leaf of "0"</li>
|
|
</ul>
