Find the mean, median and mode for the following set of scores: 24, 18, 19, 12, 23, 20, 21, 22 Share with your friends Share 0 Manbar Singh answered this The given data in ascending order is,12,18,19,20,21,21,23,24Now, mean = sum of observationsno. of observations⇒mean = 12+18+19+20+21+21+23+248 = 1588 = 19.75Now, we have number of observations, n = 8 even median =value of n2th observation + value of n2+1th observation2⇒median = value of 4th observation + value of 5th observation2⇒median = 20 + 212 = 412 = 20.5Now, we observe that the observation 21 has occurred maximum no. of times in the given data, somode of the data = 21 0 View Full Answer Mansi Thakur answered this Mean = sum of all observations/total no. of observations = 24+18+19+12+23+20+21+22/8 = 180/8 = 22.5Ascending Order: 12, 18, 19, 20, 21, 22, 23, 24n = even, therefore median = mean of (n/2)th observation + (n/2 +1)th observation = mean of 4th and 5th observations = 20+21/2 = 41/2 = 20.5Mode = 3Median - 2Mean = 3*20.5 - 2*22.5 = 61.5 - 45 = 16.5 0
