O B. There is no mode. (b) Which measure in part (a) is most representative of the data? O A. The mode is most representative of the data because the data is symmetric. O B. The mean is most representative of the data because it is not so sensitive to extreme values, like 0. O C. The median is most representative of the data because it is sensitive to extreme values, like 0. O D. The median is most representative of the data because the data is nonsymmetric
