Answer
$$mean = 3$$
$$median = 3$$
$$mode = 3$$
Work Step by Step
To calculate the mean, sum the data values in the set and divide by the number of data values in the set:
$$mean = \frac{0+0+1+1+2+3+3+5+3+8+7}{11}=\frac{33}{11}=3.$$
The median is the middle value of the data set when it is arranged in increasing or decreasing order:
$$0,0,1,1,2,3,3,3,5,7,8.$$
So
$$median = 3.$$
The mode is the value which occurs most often in the data set:
$$mode = 3.$$
