  2. Data interpretation

  3. It's the simplest form of data presentation where data are given in a table with proper heading and denominations. There is really no limit to what the tables can contain. Tabular data

  4. Tabular data

  5. Q1. In 2003 which chapter contributed maximum number of questions?Q2. What was the total number of questions asked from Inequalities chapter in the given period of time?Q3. What was the percentage contribution of P and C in year 2004 Related questions

  6. Q1 Geometry Q2 26 Q3 11.9% Answers

  7. Data representation

  8. The table pertains to the data on the production of two wheelers, year wise. The table also divides the production of the two wheelers by categories. Thus it is possible to get the picture of the production of different types of two wheelers in India About tables

  9. Contribution of each type of two wheeler towards the total, in a given year is 1999-00 = production of scooters X 100 Total production Growth of the motorcycle in India from 1998-99 to 1999-00 =Difference of production in two yearX100 Production in 1998-99 Few questions

  10. If the installed capacity is 3000000 in the year 1999-00 then the capacity utilisation in the year 1999-00 is = Production X 100 Capacity Trends of growth over the year can be achieved when we look into the growth rate of every year. Few more questions

  11. The graph indicates the variation of a parameter with respect to another. The parameters are represented on X axis and Y axis. The slope of the graph indicates the absolute growth and not the percentage growth. Simple growth is calculated by applying simple interest method. Cumulative growth method is found by compound interest formulae. Line Graphs

  12. A line graph is a way to summarize how two pieces of information are related and how they vary depending on one another. The numbers along a side of the line graph are called the scale. Each variable is plotted along an axis. A line graph has a vertical axis and a horizontal axis. For example, if we wanted to graph the number of questions asked from algebra chapter in last 6 CAT editions we would have got a graph line as shown below Line graph contd…

  14. Now few questions can be asked on above graph1. In which year maximum number of questions was asked?2. Between what time periods was the largest increase in number of questions?3. Based on your observations of the graph, make a prediction about what the number of questions might be in the year 2007. Related questions

  15. Q1 2004 Q2 2003-04 Q3 Cannot be predicted Answers

  16. Types of Line graph

  17. line graph Directions for Questions 1 to 4: Answer the questions on the basis of the information given below. The data points in the figure below represent monthly income and expenditure data of individual members of the Ahuja family ( ), the Bose family ( ), the Coomar family--( ), and the Dubey family ( ). For these questions, savings is defined as Savings = Income – Expenditure

Dubey Related questions

  20. Line graphs do not present specific data as well as tables do but line graphs are able to show relationships more clearly than tables do. Line graphs can also depict multiple series which are usually the best candidate for time series data and frequency distribution. Bar graphs and line graphs share a similar purpose. The line graph is used to show a change in direction. Graph Comparison

  21. Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a rectangular bar to represent value/requisite information. There are many characteristics of bar graphs that make them useful. Some of these are that: 1 They make comparisons between different variables and groups of data very easy to see. 2 They clearly show trends in data, meaning that they show how one variable is affected as the other rises or falls. Given one variable, the value of the other can be easily determined. A bar graph is a visual display used to compare the amounts or frequency of occurrence of different characteristics of data. This type of display allows us to make generalizations about the data quickly. Bar Graph

  30. A pie chart is a circle graph divided into pieces, each displaying the size of some related piece of information. Pie charts are used to display the sizes of parts that make up some whole. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. Together, the sectors create a full disk While the pie chart is perhaps the most widely available statistical chart in the business world and the mass media, it is rarely used in scientific or technical publications.

  35. In caselets data are given in the form of paragraph. No charts/graphs are provided with the data. Caselets vary considerably in length, in the amount of information contained, in different sentences and paragraph. While reading a caselets it s always advisable to underline the important fact and figures and if necessary make your own table/chart/graphs for solving the questions. Caselets
