Given data: 17, 23, 1, 52, 11, 11, 31, 34, 26, 9, 56, 64, 2, 1 Now, arrange the data in ascending order, we get: 1, 1, 2, 9, 11, 11, 17, 23, 26, 31, 34, 52, 56, 64 Here, the number of observations is 14, which is even Thus, median = \(\frac{ 7th + 8th }{2}\) Median = \(\frac{ 17 + 23 }{2}\) Median = 20.
