what is the mode of this set of numbers:13,11,7,9,12,5

i don't think there is a mode, because no number occurs more than once.

you might want to look up what mode is.

ther's no damn mode
umm..yur dumb
"SOORY"

I apologize if my previous response was not clear. You are correct, there is no mode in this set of numbers because no number occurs more than once. The mode is the value that appears most frequently in a set of numbers. In this case, none of the numbers repeat, so there is no mode.

To find the mode in a set of numbers, you would need to determine which number occurs most frequently. If multiple numbers have the same highest frequency, then the set is said to have multiple modes. But in this particular set, each number appears only once, so there is no mode.
