Mean Median Mode and Range
Mean is actually is a average which you can calculate by diving the count of numbers in set of data to the sum of all the number given in set of data for example data set is { 10 , 13 , 17 , 18 , 12 } Sum of all number 10 + 13 + 17 + 18 + 12 = 70 and number of numbers is 5 Mean = 70 / 5 = 14 Median is actually a middle number if numbers are arrange in a order ascending/ descending means to find the median first arrange the set of data in a order and then pick a middle number example 1 : count of number is odd data set is { 10 , 13 , 17 , 18 , 12 } arranging the set in order { 10, 12, 13, 17, 18 } median is 13 as it is a middle number example 2 : count of number is even data set is { 10 , 13 , 17 , 18 , 12 , 14 } arranging the set in order { 10, 12, 13, 14 ,17, 18 } now we have two middle numbers so take the average to find the median median is 13.5 Mode : It is the value that repeated most often. example1 :...
