How To Construct Draw Make A Vertical Horizontal Compound Bar Graph

In this video we discuss how to construct, draw, make a vertical or horizontal bar graph. We cover how to label the graph, and how to mark the graph. Transcript/notes A bar graph uses vertical or horizontal bars whose lengths represent the frequencies of the data, and this data is often qualitative or categorical. For instance you could construct a bar graph for the data in this table, the number of monthly shoe sales, for each model for a certain shoe company. Bar graphs are easy to construct, as in our example, you simply draw an x and y axis, label the x axis as shoe models, and write in the different models of shoes at equal distances from one another on the x axis. Then label the y axis units sold. Next, from the table, find the highest value in the table, 67, maybe round up to 70 and mark that somewhere near the top of the y axis. Then make 6 more marks of equal distances going down the y axis marking them 60, 50, and on down to 10. Next, you would draw in the bar for the first shoe model, sapphire, which had 22 sales. Then, draw in the next bar for the weekender shoe, which goes up to 67. If you are drawing these in by hand, make sure the bars are the same width, or at least within reason. Next would continue this process for the remaining 3 shoes. As I said earlier in this video, you could make this same bar graph in a horizontal manner as you see here. Another bar graph that is often used in statistics is a compound bar graph. A compound bar graph is used to compare data for 2 or more groups, for instance, this bar graph shows, over a 4 year span, the salaries a pro football team spent on defensive players and offensive players.
