The mode is which value happens the most commonly. So, in this case, only 8 happens more than once. Then 8 would be the mode.
For the median, we rank the values in an ascending way. The value at the midpoint is the median. So
6,7,8,8,9,10,11,14,22
The median, which is 9, separates the lower 50% from the upper 50%. In this case, the median is higher than the mode, so it cannot be the answer.
The mean and the range are weighed heavily by the outlier(the game with 22 turnovers), so they cannot be used.
The answer is the mode.
