The four statistical features considered in this study for each dataset are mean or average, standard deviation, skewness and kurtosis. Mean or average For a set of \(N\) numbers \(({X}_{1},{X}_{2}\dots {X}_{N})\), the following formula can quantify the mean or average (\(\...
Cronbach's alpha / Guttman’s statistics estimate the reliability of the scale entered as input, while the deleted items statistics provide useful information on the influence of the withdrawal of each element on the overall reliability of the scale. ...
8. Apply the Standard Error Formula The standard error is a measure of the precision of the sample mean as an estimate of the population mean. It accounts for both the variability within each group and the size of the sample. The smaller the standard error, the more reliable your estimate...
e.g., [28,29,30]. The most confusion arises from the different terminology of each work, especially regarding the often misleading usage of the term “(Likert) scale” for a multi-
Answer and Explanation: The correct solution to this problem is provided byoption C: a factor analysis. Based on the given information, the correct solution to this problem...
Quantitativedata represents amounts. These may be on aninterval scale(e.g. test score) or aratio scale(e.g. age). Many variables can be measured at different levels of precision. For example, age data can be quantitative (8 years old) or categorical (young). If a variable is coded nu...
I believe that melanoma is easy to cure I believe that melanoma can have very severe consequences Getting melanoma would be a big health threat for me A mean score will be derived from response options on a 5-point Likert scale: 1 = strongly disagree, 2 = disagree, Lo et al....

Scale in order to further depict this personality typology in real organizational contexts. Since there are no scales to measure such traits in personnel, we have followed the methodological steps for elaborating the scale’s items from the available qualitative literature and further employed a ...
The natural generalisation of the binomial distribution for overdispersed data is the beta-binomial distribution. It provides simple formulae for probabilities and derivatives of its log-likelihood function. Furthermore, there are available ready-to-use algorithms for the estimation of its parameters (...
