Find the median, mean and mode of the given data. 7, 8, 12, 10, 9, 8, 9, 11, 8, 11, 8 Share with your friends Share 0 Manbar Singh answered this The given data is,7, 8, 12, 10, 9, 8, 9, 11, 8, 11, 8.Number of observations, n=11Sum of observations=7+8+12+10+9+8+9+11+8+11+8=101Mean=sum of observationsnumber of observations=10111=9.18The given data is,7, 8, 12, 10, 9, 8, 9, 11, 8, 11, 8.By inspection, we see that the observation 8 occurs most frequently that is 4 times in the data set.So, the mode of the given data is 8.Arranging the data in ascending order, we get7, 8, 8, 8, 8, 9, 9, 10, 11, 11, 12.Number of observations, n=11, which is odd.So, median=value of n+12th observation⇒median=value of 11+12th observation⇒median=value of 6th observation⇒median=9 -1 View Full Answer
