Explain how the relationship between the mean and median provides information about the symmetry or skewness of the data's distribution. select the correct answer below. a. the median is affected by extreme values, while the mean is not. if the data set is skewed to the right, then the median is less than the mean. if the data set is symmetric, the mean equals the median. if the data set is skewed to the left, the mean is less than the median. b. the mean is affected by extreme values, while the median is not. if the data set is skewed to the right, then the median is greater than the mean. if the data set is symmetric, the mean equals the median. if the data set is skewed to the left, the mean is greater than the median. c. the median is affected by extreme values, while the mean is not. if the data set is skewed to the right, then the median is greater than the mean. if the data set is symmetric, the mean equals the median. if the data set is skewed to the left, the mean is greater than the median. d. the mean is affected by extreme values, while the median is not. if the data set is skewed to the right, then the median is less than the mean. if the data set is symmetric, the mean equals the median. if the data set is skewed to the left, the mean is less than the median.
