Data interpretation & sufficiency Medium

Directions for the following 2 (two) items: The following table gives the GDP growth rate and Tele-density data of different States of a country in a particular year. Study the table and answer the two items that follow.

With reference to the above table, which of the following is/are the most logical and rational inference/inferences that can be made?

  1. 1.Higher per capita income is generally associated with higher Tele-density.
  2. 2.Higher GDP growth rate always ensures higher per capita income.
  3. 3.Higher GDP growth rate does not necessarily ensure higher Tele-density.

A table of 18 States giving per capita income ($), GDP growth rate (%) and tele-density.
From UPSC's question paper.

Select the correct answer using the code given below.

Answer & explanation

Answer: (c) 1 and 3

Sorted by income, the richer States mostly have high tele-density: the nine highest-income States average about 85, the nine lowest about 41. State 3, with the second-highest growth rate, has the lowest per capita income, which defeats 'always' in 2; State 4 grows at 9.78% with tele-density of only 5.94, confirming 3.

  1. Statement 1: the nine richest States (6, 12, 7, 10, 5, 14, 16, 9, 1) average tele-density of about 85; the nine poorest average about 41 — a general association.
  2. Statement 2: State 3 grows at 10.83% (second highest) but has the lowest per capita income, $254 — 'always' fails.
  3. Statement 3: State 4 grows at 9.78% with tele-density 5.94, while State 14 grows at 5.46% with 97.9 — high growth does not ensure high tele-density.
  • ✓ 1. Exceptions exist (State 3 at $254 has 50.07), but 'generally' allows them; income and tele-density clearly move together across the table.
  • ✗ 2. One counter-example is enough: State 3 has the second-highest growth and the lowest per capita income.
  • ✓ 3. State 4 (9.78% growth, 5.94 tele-density) shows high growth without high tele-density.

Remember · 'Generally' tolerates exceptions; 'always' falls to one counter-example. Scan the table for a single contradicting row.
