Ex 3.2, 1 The scores in mathematics test (out of 25) of 15 students is as follows: 19, 25, 23, 20, 9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20 Find the mode and median of this data . Are they same? Arranging data in ascending order Mode Mode is maximum occurring observation Since 20 occurs 4 times, Mode = 20 Median Number of observation = 15 Since n is odd, Median = ((๐‘› + 1)/2)^๐‘กโ„Ž observation = ((15 + 1)/2)^๐‘กโ„Ž = 20 So, both mode & median are 20 Hence, they are same.
