Question

Find the median of the data: \(3,\; 11,\;7,\;2,\;5,\;9,\;9,\;2,\;10,\;15,\;7\).

Answer

Given data is \(3,\; 11,\;7,\;2,\;5,\;9,\;9,\;2,\;10,\;15,\;7\)
Arranging in ascending order, \(2,\;2,\;3,\;5,\; 7,\; 7,\;9,\;9,\;10,\;11,\; 15\)
Number of observations \(=11\) i.e. an odd number.
Thus, Median is the middle most term which is the \(5^{th}\) term fram both end.
Hence, median \(=7\).
