Negatively skewed', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Negatively skewed For a symmetric curve such as gaussian - mean, median and mode coincide. That is, they are the same value. - A skewed distribution will have different mean, median and mode. In fact, very different values of mean, median and mode is a clear indication of skewness. In positive skew, mean>median>mode. In negative skew, mean<median<mode.', 'role': 'assistant'}]
