Question

what is the mode of this set: 2,5,4,6,3,7,9,10
2,3,4,5,6,7,9,10 5.5
not enough information 5.8

Explanation:

Step1: Define mode

The mode is the value that appears most frequently in a data set.

Step2: Check frequency of each value

For the set $\{2,5,4,6,3,7,9,10\}$, every number occurs exactly 1 time.

Step3: Determine result

When all values occur with the same frequency, there is no unique mode, or we say all values are modes of the set.

Answer:

A. 2,3,4,5,6,7,9,10
