set of numbers\tmean\tmedian\tmode
2, 5, 7, 7, 9\t6\t7\t7
5, 2, 8, 3, 2, 7, 1\t\t3\t
6, 1, 12, 4, 12\t\t\t
6, 6, 14, 10, 4\t\t\t
9, 8, 1, 7, 3, 7, 3, 4, 3\t\t\t

Explanation:

Step1: Calculate mean for 5,2,8,3,2,7,1

Sum = 5+2+8+3+2+7+1 = 28; Mean = 28/7 = 4

Step2: Find mode for 5,2,8,3,2,7,1

Most frequent number: 2

Step3: Calculate mean for 6,1,12,4,12

Sum =6+1+12+4+12=35; Mean=35/5=7

Step4: Find median for 6,1,12,4,12

Sorted: 1,4,6,12,12; Middle value=6

Step5: Find mode for 6,1,12,4,12

Most frequent number:12

Step6: Calculate mean for 6,6,14,10,4

Sum=6+6+14+10+4=40; Mean=40/5=8

Step7: Find median for 6,6,14,10,4

Sorted:4,6,6,10,14; Middle value=6

Step8: Find mode for 6,6,14,10,4

Most frequent number:6

Step9: Calculate mean for 9,8,1,7,3,7,3,4,3

Sum=9+8+1+7+3+7+3+4+3=45; Mean=45/9=5

Step10: Find median for 9,8,1,7,3,7,3,4,3

Sorted:1,3,3,3,4,7,7,8,9; Middle value=4

Step11: Find mode for 9,8,1,7,3,7,3,4,3

Most frequent number:3
