![]() ![]() Stemplots show a little more information than a histogram and have been a common tool for displaying data sets since the 1970s. It creates vertical lines from a baseline to the Y-coordinate and places a marker at the tip. How to Make One Descriptive Statistics > Stemplot / Stem and Leaf Plot What is a Stemplot A stemplot is like a histogram they are both tools to help you visualize a data set. Bar graphs are especially useful when categorical data is being used. To plot a stem plot in Matplotlib, we can use stem() method. Some bar graphs present bars clustered in groups of more than one (grouped bar graphs), and others show the bars divided into subparts to show cumulative effect (stacked bar graphs). One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value. A bar graph is a chart that uses either horizontal or vertical bars to show comparisons among categories. That is, finding a general pattern in data sets including temperature, sales, employment, company profit or cost over a period of time. These graphs are useful for finding trends. A line graph is often used to represent a set of data values in which a quantity varies with time. The advantage in a stem-and-leaf plot is that all values are listed, unlike a histogram, which gives classes of data values. In a stem-and-leaf plot, all data values within a class are visible. ![]() The frequency points are connected using line segments.Ī stem-and-leaf plot is a way to plot data and look at the distribution. import matplotlib.pyplot as plt import numpy as np x np.linspace(0. ![]() In the particular line graph shown in Example, the x-axis (horizontal axis) consists of data values and the y-axis (vertical axis) consists of frequency points. stem plots vertical lines from a baseline to the y-coordinate and places a marker at the tip. Highlight just the header cells, which may say “Stem” and “Leaf” or “Leaves.” Click the “Borders” button on the ribbon and choose “Bottom Border.” This gives the header cells an underline and separates them from the rest of the data.\): Atlanta Hawks Wins and Losses Number of WinsĪnother type of graph that is useful for specific data values is a line graph. This takes the borders off the grid and leaves you with just the stem and leaf plot data. For example, if you want to make a stem-and-leaf plot for the data set of 100, 105, 110, 120, 124, 126, 130, 131, and 132, you can use the highest place value to create the stem. A two-dimensional stem plot displays data as lines extending from a baseline along the x axis. Click the “Plain Table 4” option in the Table Styles section of the ribbon. Click the Design tab if it is not enabled. You can also click the Home tab and format them in a different color.Ĭlick the table to open the Table Tools tab at the top of the work area. Press the “Ctrl-B” keys to boldface the headers to separate them from the rest of the table. You may need to format the numbers after they paste in or make cell shifts if you’re pasting from a differently-sized table. If you have this data already typed, such as in an Excel spreadsheet, you can copy and paste it into the Word table. Type the related data.Ĭontinue until you’ve typed the entire stem and leaf data. Press “Tab” and you’ll move into that cell’s corresponding “Leaf” cell to its right. If you created a table with additional columns, type those headers.Ĭlick into the first cell under the first column header and type that cell’s data. Type “Leaf” or “Leaves” or your preferred header. Press the “Tab” key to move you into the next cell, the second header. ![]() Click into the first cell in the table and type “Stem” or your preferred header for that column. ![]()
