A data set is a collection of responses or observations from a sample or entire population.. Mode is a value that occurs most frequently in a set of, observation, that is, the observation, which has maximum, frequency is called mode. The formal normality tests including Shapiro-Wilk test and Kolmogorov-Smirnov test may be used from small to medium sized samples (e.g., n < 300), but may be unreliable for large samples. In conclusion by applying the sampling distribution of difference between sample means and the normal distribution with means obtained from the benchmarking test could statistically prove the most efficient implementation Module Catalogues Human Resources System server. 3.1 Descriptive Statistics Measures of dispersion such as variance reveal how observations of a random variable deviate from their mean. The results showed that 18% of nursing professionals are at risk for developing metabolic syndrome. If a variable fails a normality test, it is critical to look at More about the basic assumptions of t-test: normality and sample size. This study examined the relationship among survivor attributes (attitude, commitment and motivation) after downsizing in selected manufacturing organizations. Student performances were lower particularly in the pictorial representation test than the other two. 2. Three methodologies which are Support Vector Machine, Artificial Neural Network, and k-Nearest Neighbour are proposed for the algorithm of the predictive model. The results showed that survivors had high levels of motivation and moderate to satisfactory levels of attitude and motivation. [Last accessed on 2018 Aug 02].
