8. ADVANTAGES: Visually strong Can easily compare two or three data sets

9. DISADVANTAGES: Graph categories can be reordered to emphasize certain effects Use only with discrete data

11. KINDS OF BAR GRAPH VERTICAL BARS HORIZONTAL BARS

12. VERTICAL BARS Vertical bars are generally used for chronological comparisons

20. OBJECTIVES IN CONSTRUCTING BAR GRAPH: AFTER COMPLETING THIS UNIT, IF YOU ARE GIVEN A TABLE INFORMATION THAT IS TO BE DISPLAYED AS A BAR, YOU SHOULD BE ABLE TO:

21. IDENTIFY THE BAR GRAPH TITLE. IDENTIFY LABELS FOR THE BAR GRAPH AXES. IDENTIFY INFORMATION GIVEN BY A DESIGNATED BAR. DETERMINE THE SCALE OF A BAR GRAPH. CONSTRUCT A BAR GRAPH.

22. PARTS OF BAR GRAPH

24. STEPS FOR CONSTRUCTING A BAR GRAPH: 1.) DETETMINE THE FF. ELEMENTS OF THE GRAPH FROM THE TABLE TITLE OF THE GRAPH QUARTERLY INCOME of ASIA COLLEGE INSURANCE PLAN

25. LABEL FOR EACH AXIS--- HERE WE MUST DETERMINE WHICH IS TO BE THE FREQUENCY AXIS AND WHICH IS TO BE THE GROUPED DATA AXIS Sales in Million Pesos FREQUENCY GROUP DATA AXIS QUARTERS OF THE YEAR

26. SCALE FOR EACH AXIS– DETERMINE THE NUMERICAL SCALE FOR THE FREQUENCY AXIS, THEN THE GROUP NAMES FOR GROUPED DATA AXIS 120 100 80 60 40 20 0 1 ST QTR. 2 ND QTR.3 RD QTR.4 TH QTR.

27. 2.) DRAW A SET OF AXES THAT YOU WILL USE TO CONSTRUCT YOUR GRAPH DETERMINE WHICH AXIS WILL BE THE FREQUENCY AXIS– DETERMINE WHETER BARS WILL GO HORIZONTALLY OR VERTICALLY. 120 100 80 60 40 20 0 1 ST QTR.2 ND QTR.3 RD QTR.4 TH QTR

31. SUMMARY Bar graphs can be used to display a wide variety of information. When data is represented in the form of a bar graph the human eye finds it very easy to compare the data and quickly draw conclusions. In short they are a great visual aid and will add a touch of professionalism to any web page or document which requires the display of data.
