$$mean = 3$$ $$median = 3$$ $$mode = 3$$

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: $$mode = 3.$$
