A positive skewness is the right-skewed distribution with the long tail on its right side. The value of skewness of data for a positively skewed distribution is greater than zero. As you might have already understood by looking at the figure, the value of the mean is the greatest one, fol...

Specifically, we noticed that no outliers were present in the data set, and any missing data were addressed through mean imputation, as the proportion of missing data was less than 1% for all variables [53]. The skewness and kurtosis values (see Table 1) for all variables were assessed, ...

There are growing efforts amongst educators and especially researchers in gamification and maker spaces to ensure that learning environments are fun and enjoyable. Accordingly, efforts to evaluate whether students enjoyed a certain learning activity are often an important aspect of innovations. However, th...

Kurtosis Kurtosis is a measure of the combined weight of a distribution's tails relative to the rest of the distribution. In Figure 2 below, the distribution on the left exhibits negative kurtosis, indicating a lower probability of results around the mean, and lower probability of extreme val...
Right skewness. Normal Distributions and Asset Returns When a portfolio of investments is put together, it is assumed that the distribution of returns will follow a normal distribution. Under this assumption, the probability that returns will move between the mean and three standard deviations, either...
