Dengan demikian Kurtosis. , May be one of 1 In statistics, skewness is a measure of the asymmetry of the probability distribution of a random variable about its mean. WebThe analysis for the current study showed that the skewness and kurtosis values for each variable were within acceptable limits, and the data showed a normal distribution (see Table 5). For instance, robustness to these kinds of violations of normality partly depends on whether the group sizes are The difficulty is that skewness and kurtosis are dependent; their effects can't be completely separated.
