Skewness measures the lack of symmetry in a data distribution. It indicates that there are significant differences between the mean, the mode, and the median of data. Skewed data cannot be used to create a normal distribution.27. What is kurtosis?
9. A normal distribution has coefficients of skewness and excess kurtosis which are respectively (a) * 0 and 0 (b) 0 and 3 (c) 3 and 0 (d) Will vary from one normal distribution to another 10. Which of the following would probably NOT be a potential “cure” for non-normal residua...
central tendency and measures of variability are two types of descriptive statistics (spread). The mean, median, and mode are examples of measurements of central tendency, whereas standard deviation, variance, minimum and maximum variables, kurtosis, and skewness are examples of measures of ...

Statement 3: Standard deviation is an inadequate measure of risk for evaluating the performance of hedge funds, because hedge funds’ return distributions exhibit negative skewness and negative excess kurtosis. Nagoree feels that the fees charged by hedge fun...
( Many other useful statistics can be computed including the standard deviation, the variance, skewness, kurtosis. But we will not be computing those.) For example, given this set of 6 numbers : { 5, 7, 1, 3, 6, 2 }, each of the metrics...
However, dealing with Skewness and Kurtosis might not always be the solution to improve the model's performance. *We deal with skewness and kurtosis to make the data follow the Gaussian distribution. This simply transforms the data applicable to the largest set of techniques, such as statistical...
