Find Median for the above data. Median= size of n/2 th observation which lies in the class 20-30 Question no.13 Consider the data set: 67 25 42 57 38 49 36 29 61 31 71 53 73 84 87 Find the 50th percentile point. First arrange the data in ascending order 25 29 31 36 38 42 49 53 57 61 67 71 73 84 87 Location of 50th Percentile is (15+1) (50/100) = 8th value = 53 Question no.14 Give a five number summary of the data. 15, 17, 18, 19, 35, 25, 14, 45, 37, 51, 42 Re arrange data in ascending order 14, 15, 17, 18, 19, 25, 35, 37, 42, 45, 51 Minimum = 14 First Quartile = ( 11+1)(25/100) = 3rd position = 17 Median = 25 Third Quartile = (11 + 1) ( 75/100) = 9th position = 42 Maximum = 51
