This graph depicts the last eight years' annual salaries (in Rs. lacs.) offered to students during campus placement. Every year 100 students go through placement process. However, at least one of them fails to get placed. The salaries of all unplaced students are marked zero and represented in the graph.
[Chart in source: 'Salaries at various years' - stacked bars per year showing Bottom 25 salaries, 26th position to median salary, Higher than median salary to 75th position, and Top 25 salaries, with a bold line for the mean salary - see page 20 of source PDF.]
Approximate values read from the chart (25th-position salary / median / 75th-position salary / maximum / mean), in Rs. lacs:
2008: 9 / 14 / 27 / 30 / 17
2009: 10 / 24 / 32 / 34 / 17
2010: 11 / 22 / 25 / 37 / 18
