Ppt On Data Interpretation For Cat
- 1. DATA INTERPRETATION LECTURE - 2
- 2. TWO-VARIABLE GRAPHS Here the data will be represented in the form of a graph. Generally it represents the change of one variable with respect to the other. Look at the following graph: Car sales in India in different years (in 000s) 200 150 100 50 0 2003 2004 2005 2006 Maruti Hyundai Others
- 3. From the given graph, we can calculate 1. The percentage change in the sales of any brand from one year to another. EXAMPLE: 200 What is the percentage increase in Maruti sales 150 from 2004 to 2006? 100 (1) 50% 50 (2) 75% 0 2003 2004 2005 2006 (3) 100% Maruti Hyundai Others (4) 125%
- 4. From the given graph, we can calculate 2. Rate of growth of total car sales (all the brands) in a given period. EXAMPLE: 200 What is the approximate 150 percentage change in the 100 sales of all the given brands together from 2003 50 to 2006? 0 2003 2004 2005 2006 (1) 100% Maruti Hyundai Others (2) 120% (3) 160% (4) 200%
- 5. From the given graph, we can calculate 3. The proportion of the sales of any brand with respect to the sales of any other brand in the given year. EXAMPLE: 200 In 2006, the sales of 150 Hyundai is approximately what percentage less than 100 the sales of Maruti? 50 (1) 25% 0 2003 2004 2005 2006 (2) 42.9% Maruti Hyundai Others (3) 60% (4) 75%
- 6. From the given graph, we can calculate 4. For a given brand, the year in which the sales increased by maximum percentage over the previous year. EXAMPLE: In which year the sales of 200 Maruti increased by 150 maximum percentage over 100 the previous year? 50 (1) 2004 0 (2) 2005 2003 2004 2005 2006 (3) 2006 Maruti Hyundai Others (4) All are same
- 7. From the given graph, we can calculate 5. In a given year the brand which has noted the maximum growth rate in the sales over the previous year. EXAMPLE: For which brand, the growth 200 rate in the sales is maximum 150 from 2005 to 2006? 100 (1) Maruti 50 (2) Hyundai 0 (3) Others 2003 2004 2005 2006 (4) Both Maruti and Hyundai Maruti Hyundai Others
- 8. BAR-CHART Bar-chart is also one of the ways to represent data. The data given in the above graph can also be represented in the form of a bar-chart as shown below. 200 175 150 125 100 100 100 90 100 80 60 60 50 50 50 30 0 2003 2004 2005 2006 Maruti Huyndai Others Here also we can deduce all the parameters as we could do in the case of a two-variable graph.
- 9. From the given graph, we can calculate 1. Percentage change in the sales of any brand from one year to an other. EXAMPLE: 200 175 What is the percentage increase in the sales of 150 125 Maruti from 2004 to 2006? 100 100 80 100 100 90 60 60 (1) 50% 50 50 30 50 (2) 75% 0 (3) 100% 2003 2004 2005 2006 (4) 125% Maruti Huyndai Others
- 10. From the given graph, we can calculate 2. Rate of growth of total sales of the cars (all the brands) in a given period. EXAMPLE: What is the approximate 200 175 percentage change in the 150 125 sales of all the given 100 100 100 90 100 80 brands together from 2003 50 60 50 60 to 2006? 50 30 (1) 100% 0 (2) 120% 2003 2004 2005 2006 (3) 160% Maruti Huyndai Others (4) 200%
- 11. From the given graph, we can calculate 3. Proportion of the sales of any brand with respect to those of any other brand in the given year. EXAMPLE: In 2006, the sales of 200 175 Hyundai is approximately 150 125 what percentage less than 100 80 100 100 90 100 the sales of Maruti? 50 60 50 60 50 30 (1) 25% 0 (2) 42.9% 2003 2004 2005 2006 (3) 60% Maruti Huyndai Others (4) 75%
- 12. From the given graph, we can calculate 4. For a given brand, the year in which the sales increased by a maximum percentage over the previous year. EXAMPLE: In which year the sales of 200 175 Maruti increased by a 150 125 maximum percentage over 100 100 100 90 100 80 the previous year? 50 60 50 60 30 (1) 2004 50 (2) 2005 0 2003 2004 2005 2006 (3) 2006 Maruti Huyndai Others (4) All are same
- 13. From the given graph, we can calculate 5. In a given year the brand which has noted the maximum growth rate in the sales over the previous years. EXAMPLE: For which brand the growth 200 175 rate in the sales is maximum 150 125 from 2005 to 2006? 100 100 80 100 100 90 60 60 (1) Maruti 50 50 30 50 (2) Hyundai 0 (3) Others 2003 2004 2005 2006 (4) Both Maruti and Hyundai Maruti Huyndai Others
- 14. VENN DIAGRAMS If the information comes under more than one category, we represent such data in the form of a Venn diagram. The following Venn diagram represents the number of people who speak different languages. Hindi (80) English (120) 32 10 25 12 Punjabi (125)
- 15. From the given diagram, we can find 1. The number of people who can speak only English. 2. The number of people who can speak only Punjabi. EXAMPLES: How many people speak only English? Hindi (80) English (120) 32 10 (1) 22 (2) 73 25 (3) 47 (4) 120 12 How many people speak only Punjabi? Punjabi (125) (1) 37 (2) 50 (3) 75 (4) 125
- 16. From the given Venn diagram, we can find 3. The number of people who can speak both Punjabi and Hindi. 4. The number of people who can speak exactly two of the three languages. EXAMPLES: How many people can speak English (120) Hindi (80) both Punjabi and Hindi? 32 10 (1) 9 (2) 12 25 (3) 13 (4) 38 12 How many people can speak exactly two languages out of the Punjabi (125) given three? (1) 25 (2) 35 (3) 60 (4) 80
- 17. From the given Venn diagram, we can find 5. The number of people who can speak at least two languages. 6. The number of people who can speak exactly one or two languages. EXAMPLES: How many people in the colony speak at least two of the above three languages? Hindi (80) English (120) (1) 25 (2) 35 32 10 (3) 60 (4) 80 25 12 How many people in the colony speak only one language? Punjabi (125) (1) 32 (2) 73 (3) 75 (4) 180
