23 is, because it is the most common number in the list.
What you have to do is you find the number that accrues most often. ex. You have the numbers 34,45,34,65,43,29,and 27, the mode would be 34 because there is 2 34's. But say there is more then 1 number it is both. ex. Say you have the numbers, 23,34,28,23,26,28 and 32, the mode would be both 23 and 28.If there is 3 numbers than it would be all of them.ex,You have the numbers 25,97,25,32,74,35,74,97.The mode would be 25,97 and 74.
The mode of the set of numbers {31, 34, 34, 35, 36} is 34, as it is the number that occurs the most.
That set has no mode.
23 and 11
17 because it's repeated...... 26 17 34 10 & 17
It is 10, the middle value between the two middle numbers.
How about: 23+34 = 57
21, 31, 31, 33, 34, 42 Mean: 32 Median: 32 Mode: 31
All of the numbers appear once and as a mode is the most commonly occurring number, there is no mode.
Range: 34 Mean: 21.71 Median: 15 Mode: 10
25
23, 34, 45, 56
