This document provides instructions for creating a frequency table and bar graph. It explains that a frequency table lists data values in order from least to greatest along with their frequencies. An example frequency table is given using student survey data on favorite foods. The document then defines a bar graph and explains it can be used to compare and display data. It provides directions for labeling the axes and scales and drawing the bars proportionally based on the frequencies.
1. How to Make a Frequency Table and Bar Graph By: Amanda Craft and Betsy Lawson
2. Frequency Table The frequency of a data value is equal to the number of times that the value occurs A Frequency Table arranges data values in order from least to greatest with their corresponding frequency
3. Example If given this data The Frequency table would look like this Student survey
4. Bar Graphs Definition: A Graph consisting of vertical or horizontal bars that proportionally represent a set of data Use: to compare and display data Vertical Horizontal
5. Labeling Make a title for your graph Label each axis Determine a scale for the X and Yaxis Favorite Foods Y Frequency x Types of Food
6. Labeling the Y-axis: Because the frequency of the data is between 0 and 8, a good scale for this graph would be 0-8 Labeling the X-axis: use each option as a category Favorite Foods Y 8 7 6 5 4 3 2 1 0 Frequency x Pizza Cake Potato Chips Cheese Burger Cookies Ice Cream Types of Food
7. Drawing the Bars Draw a bar for each category proportional to its frequency (EX: Pizza has a frequency of 7, so we draw a bar starting at 0 and ending at 7 Favorite Foods Y 8 7 6 5 4 3 2 1 0 Frequency x Pizza Cake Potato Chips Cheese Burger Cookies IceCream Types of Food
