The correct answer is $14$. The maximum value is the largest value in the data set. The frequency refers to the number of times a data value occurs. The given frequency table shows that for this data set, the data value $6$ occurs three times, the data value $7$ occurs three times, the data value $8$ occurs eight times, the data value $9$ occurs eight times, the data value $10$ occurs nine times, the data value $11$ occurs eleven times, the data value $12$ occurs nine times, the data value $13$ occurs zero times, and the data value $14$ occurs six times. Therefore, the maximum data value in the data set is $14$.
