题目 In a positively skewed distribution, what is the order (from lowest value to highest) for the distribution’s mode, mean, and median values? A. Mean, median, mode. B. Mode, median, mean. C. Mode, mean, median. 相关知识点: 试题来源: 解析 B 略 反馈 收藏 ...
Right, skew is also known as positive skew. Positive skew has a longer or fatter tail on the right of the distribution. In a positive skew, the mean is typically greater than the median - this is due to values in the tail which naturally affect the mean more than the median. Left ske...
A skewed distribution is an uneven, asymmetrical probability distribution. It can have a positive or negative skew, depending on...
With right-skewed distribution (also known as "positively skewed" distribution), most data falls to the right, or positive side, of the graph's peak. Thus,the histogram skews in such a way that its right side (or "tail") is longer than its left side. Example of a right-skewed histogr...

Skewness risk is the risk that a model assumes a normal distribution of instrument returns when in fact the returns are skewed to the left or right of the mean. A positive skew indicates that the tail on the right side is longer than the left side and the bulk of the values lie to th...
Positive Skewness:Occurs when the tail on the right side of the data distribution is longer or fatter. Negative Skewness:Occurs when the tail on the left side of the data distribution is longer or fatter. Outliers:Data points that lie an abnormal distance from other values in a random sample...
3, this sum score is continuously distributed in the normative sample (N = 1000; Morey, 1991), and in this sense represents a depression dimension. The sum score appears very similar to a normal distribution, albeit more positively skewed as one would expect of a psychopathology scale. ...
quantity. This explains why data skewed to the right has positive skewness. If the data set is skewed to the right, the mean is greater than the mode, and so subtracting the mode from the mean gives a positive number. A similar argument explains why data skewed to the left has negative...
SAMPLE ANSWERS: A right skewed distribution means that... the mean is to the right of the median. OR the mean is lower (smaller value) than the median. OR the mean is pulled down because of the larger data outlying to the right of the majority of the data. SAMPLE ANSWERS: A right ...
