Ans. 116 (A) Write notes on : Line graph. (Sept. ’08) 1. Statistical data is determined with the help of points according to the place and time. 2. By joining these points the resultant graph is called a line graph. 3. There are two types of line graphs, namely simple line graph and multiple line graph. 4. When many lines are represented on the same graph, it is know as a multiple line graph. 5. The statistical data used for multiple line graph as per place and time represents sub-factors of a factor, or several factors. 6. Each factor or sub-factors are shown by one line and two or more than two such lines are shown on the same graph paper. SCHOOL SECTION MT 2. Ans. 3. Ans. 4. Ans. 5. Ans. 6. Ans. EDUCARE LTD. GEOGRAPHY Multiple line graph. 1. When many lines are represented on the graph, it is known as a multiple line graph. 2. The statistical data used for multiple line graph as per place and time represents sub-factors, of a factor, or several factors. 3. Each factor or sub-factor are shown by one line and two or more than two such lines are shown on the same graph paper. 4. While representing the factors in this graph, each line is shown differently and these are given in the key. 5. In this manner, variations in the factors and sub-factors and changes in them can be understood at a glance. 6. Multiple line graph is useful to compare different factors. Bar graph. 1. When the statistical data is represented on the graph paper by means of bars, it is called a bar graph. 2. The place and time is represented on ‘X’ axis and the statistical data is represented according to the scale on ‘Y’ axis. 3. By considering the data according to the place and time, the points are determined and bars of uniform thickness and uniform interval are drawn. 4. Distance between two bars should be less than the thickness of the bar. Simple bar graph. 1. The statistical data of a factor according to the place and time can be shown by various bars on the graph. 2. The place or time are shown along ‘X’ axis and the data is represented according to the scale on ‘Y’ axis. 3. The scale is determined according to maximum and minimum values. 4. Points are fixed according to the statistical values. 5. Straight lines are drawn from ‘X’ axis and special thickness is given to them. 6. All bars in this graph are of uniform thickness. Multiple bar graph. 1. In some cases comparison has to be made between two or more factors or sub-factors. 2. When many bars are shown along side each other on the same graph paper, they are called Multiple bar graphs. 3. Based on the given statistical data, one or more bars are drawn adjacent to each other. 4. In order to identify each bar they are shaded differently and the key is given accordingly. Compound bar graph. 1. When the sub-units of one geographical factor are represented by different shades on one bar, it is called a Compound bar graph. SCHOOL SECTION 117 MT GEOGRAPHY 2. 3. 4. EDUCARE LTD. In this, total of all the sub-factors is made and a complete bar is drawn. The sub-divisions of the bar are drawn based on the values. Many bars are used to show various places or different periods. Q.2 1. Ans. (B) Answer in detail : What are the methods used to represent statistical data? Following methods are used to represent statistical data : 1. One dimensional diagrams : Line graphs, bar graphs. 2. Two dimensional diagrams : Divided circles, proportionate squares and circles, divided rectangle. 3. Three dimensional diagrams: Spheres, cubes, block piles etc. 4. Distributional maps : Dot method, choropleth method etc. Q.3 1. (A) Draw a simple Line graph with the following information. Yrs.
