Answer:
7
Explanation:
The mode is the most frequently occurring value in a set of data. In this case, the number 7 occurs twice, which is more than any other number, so the mode is 7. It is worth noting that if there were no values that occurred more than once, then there would be no mode for the data set. In this case, the data set has a single mode, but it is possible for a data set to have multiple modes if there are multiple values that occur with the same highest frequency.
