TABLES

Different Types of Questions

I. TABLES

The most common representation of data is done in the form of tables. This is nothing but arranging data in rows and columns so that it is easily comprehensible.

 

Take a look at the following data. Merely arranging it in rows and columns can help us determine the trend from 2001 to 2007. We can see whether the employment in different sectors is increasing or decreasing. If we add up the totals, we can see whether the total employment in the country is increasing, and if so, we can find the increase percentage. We can also attempt some questions based on the data.

1. The rate of unemployment was the highest in

        (1) 2001           (2) 2003           (3) 2005           (4) 2007

 

2. The number of employable showed the highest percentage increase in the year

        (1) 2006-07              (2) 2005-06              (3) 2003-04              (4) 2001-02

 

3. From 2004 to 2007, we can say that:

        (1) employment numbers have fluctuated.

        (2) employment in organised sector has shown steady increase.

        (3) figures in all three categories have shown a steady increase.

        (4) Cannot reach any of the above conclusions.

 

How to Attempt:

 

1. First, take a look at the figures. Note that they are in millions.
 

Second understand what the table is saying. It is giving employment figures. This reading will help you prevent mistakes. For instance, in this case, the tendency is to tick 2007,   which gives the highest figures in the given years.
 

However, the question asked is on unemployment. So we have to figure out how to      calculate rate of unemployment.
 

A little thought is required here. Rate of unemployment would be = unemployed/total. So we have to calculate this ratio for the given choices.
 

        In 2001 it is: 15.4/76.7 = 20% approx.

        In 2003 it is: 25.5/76 = 33% approx,

        In 2005 it is: 24.8/110 = 23% approx,


And in 2007 it is: 24.8/144 = 16% approx. Hence highest unemployment rate is for 2003.

 

2. To calculate percentage increase, we always use the formula:

    [(Last value โ€“ Initial value) รท (Initial value)] ร— 100

    So we must get all the values first.

    If we add up the employed, we get (taking approximate values from 2001 to 2007):

    61, 70, 51, 73, 85, 100, 120.
 

By visual inspection, we can see that the highest increase has been for 2003-04 (almost 50%).

 

3. This is a visual question. Check the choices one by one. We see that the third choice is   wrong, since figures have not shown a steady increase in all categories. We also see that figures have not fluctuated, even though there is a fall in one year. Only choice

 

(2) is correct, since employment in organised sector has shown steady increase (visual         question).

 

What to keep in mind

Following are the main parts of the table along with suitable comments which will help in preparing an idea table from a given data.

 

(i) Title: It describes what the data is about. Very often the terms asked will become clear just by looking at the title.

 

(ii) Units: The students must always pay attention to the measurement along with the mode of rounding up. Sometimes students make mistakes when the calculation is correct but the units are wrong. Take full care whether it is Rs 150 lakh of Rs 150 crore! (both choices will of course be given)

 

(iii) Body: Pay special attention to years, growth rates and averages. The skill of the student is to locate the cell in which the question is referring to.

 

(iv) It is advisable to spend a little time to look at footnotes or information about units so as not to make a mistake.
