Stemplots became more commonly used in the 1980s after the publication of <a href="/wiki/John_Tukey" title="John Tukey">John Tukey</a>'s book on <i><a href="/wiki/Exploratory_data_analysis" title="Exploratory data analysis">exploratory data analysis</a></i> in 1977.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> The popularity during those years is attributable to their use of <a href="/wiki/Monospaced" class="mw-redirect" title="Monospaced">monospaced</a> (typewriter) typestyles that allowed computer technology of the time to easily produce the graphics. Modern computers' superior graphic capabilities have meant these techniques are less often used. </p><p>This plot has been implemented in Octave<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> and R.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> </p><p>A stem-and-leaf plot is also called a <b>stemplot</b>, but the latter term often refers to another chart type. A simple stem plot may refer to plotting a matrix of <i>y</i> values onto a common <i>x</i> axis, and identifying the common<i> x</i> value with a vertical line, and the individual <i>y </i>values with symbols on the line.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">&#91;</span>4<span class="cite-bracket">&#93;</span></a></sup> </p><p>Unlike histograms, stem-and-leaf displays retain the original data to at least two significant digits, and put the data in order, thereby easing the move to order-based inference and <a href="/wiki/Non-parametric_statistics" class="mw-redirect" title="Non-parametric statistics">non-parametric statistics</a>. <br /> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Construction">Construction</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Stem-and-leaf_display&amp;action=edit&amp;section=1" title="Edit section: Construction"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>To construct a stem-and-leaf display, the <a href="/wiki/Observations" class="mw-redirect" title="Observations">observations</a> must first be sorted in ascending order: this can be done most easily if working by hand by constructing a draft of the stem-and-leaf display with the leaves unsorted, then sorting the leaves to produce the final stem-and-leaf display. Here is the sorted set of data values that will be used in the following example: </p> <dl><dd>44, 46, 47, 49, 63, 64, 66, 68, 68, 72, 72, 75, 76, 81, 84, 88, 106</dd></dl> <p>Next, it must be determined what the stems will represent and what the leaves will represent. Typically, the leaf contains the last digit of the number and the stem contains all of the other digits. In the case of very large numbers, the data values may be rounded to a particular <a href="/wiki/Place_value" class="mw-redirect" title="Place value">place value</a> (such as the hundreds place) that will be used for the leaves. The remaining digits to the left of the rounded place value are used as the stem. </p><p>In this example, the leaf represents the ones place and the stem will represent the rest of the number (tens place and higher). </p><p>The stem-and-leaf display is drawn with two columns separated by a vertical line. The stems are listed to the left of the vertical line. It is important that each stem is listed only once and that no numbers are skipped, even if it means that some stems have no leaves.

They retain (most of) the raw numerical data, often with perfect integrity. They are also useful for highlighting <a href="/wiki/Outlier" title="Outlier">outliers</a> and finding the <a href="/wiki/Mode_(statistics)" title="Mode (statistics)">mode</a>. However, stem-and-leaf displays are only useful for moderately sized data sets (around 15–150 data points). With very small data sets a stem-and-leaf displays can be of little use, as a reasonable number of data points are required to establish definitive distribution properties. A <a href="/wiki/Dot_plot_(statistics)" title="Dot plot (statistics)">dot plot</a> may be better suited for such data. With very large data sets, a stem-and-leaf display will become very cluttered, since each data point must be represented numerically.
