You can put this solution on YOUR website! Step 1: place the numbers in order: 1,1,3,4,4,8,9,9,10
Mean = the sum of the numbers divided by the number of numbers (the average) = (1+1+3+4+4+8+9+9+10)/9 = 49/9 = 5.44
Median = the middle number = 4.
Mode is the number that appears most frequently. This set has multiple modes {1,4,9}
Range = the largest - the smallest = 10 -1 = 9.
Midrange = the mean of the largest and smallest = (10+1)/2 = 11/2 =5.5
Hope the solution helped. Sometimes you need more than a solution. Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.)
