How does the median decrease by 0.5?
Here, SET A ={−7, −4, −1, 0, 5, 8, 10, 10, 13, 21} , and median = \(\frac{{5+8}}{2} = 6.5\)
As we are assuming \(x = 3\)
the new SET A =\((-7, -1 ,-1, 3, 5, 11, 5, 5, 8, 16) = ( -7, -1, -1, 3, 5, 5, 5, 8, 11, 16)\) ( Subtracting X from 3 largest numbers in the list and x is added to the 3 smallest even numbers )
median = \(\frac{{5+5}}{2} = 5\)
Therefore the median decreased by \(0.5\)
You can pick any value for X and the median will decrease
