Tabular data

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.

About tables

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


9

Few questions

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


10

Few more questions

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.


11

Line Graphs

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.


12

Line graph contd…

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

Graph Comparison

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.


21

Bar Graph

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.

3 Given one variable, the value of the other can be easily determined.

4 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.

Pie chart

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 diskWhile 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.

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.

People Power Corporation presently employs three Managers (A, B and C) and five recruitment agents (D, E, F, G and H). The company is planning to open a new office in San Jose to manage placement of software professionals in the US.

The following information was available to the HR department of People Power Corporation.

• Managers A and C are at each others throat and therefore cannot be sent as a team to the new office.

• C and E are excellent performers in their own right. However, they do not function together as a team. They should be separated.

• D and G have had a major misunderstanding during the last office picnic. After the picnic these two have not been in speaking terms and should therefore not be sent as a team.

• D and F are competing for a promotion that is due in another 3 months. They should not be a team
