Will a set of data always have a mode? explain your answer.

No

Step-by-step explanation: Unlike the mean and median of a data set, it's completely possible for a data set to have no mode. Remember, the mode is the number that appears most frequently in a data set.

I'll show you an example of a data set that has no mode.

In the image provided, you will see that each of the numbers appear only once. In this situation, we would just write no mode.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
