Select your citation The Statistician, 47, 183189. 5 (b)) reflects the degree of abundance of coarse and fine-grained sediment particles, while graphic kurtosis (KG) reflects the peakedness or the sharpness of the grain size distribution (Folk, 1966). Arguments passed to or from other methods. The kurtosis of a normal distribution is 3. V Space With Norm $||*||$ - Fourier Series. dari sampel salesman door to door PT. The study has found that the mean and SD of all the items was in an acceptable range and that skewness and kurtosis coefficients are below 1 and 1.5, respectively. Acceptable values of skewness fall between 3 and + 3, and kurtosis is appropriate from a range A positive value means the distribution is positively skewed.
