The Assumption of Normality
We conducted a statistical test of the assumption of normality by calculating skeswness and kurtosis. For both kurtosis and skewness, values between -2 and +2 are considered “acceptable,” indicating that the level of kurtosis or skewness is consistent with that of a normal distribution. These tests were necessary in order to determine whether ANOVA could be used to compare the sample. In the study, the skewness and kurtosis for the variables are within the values range of -2 through +2. Thus, the data have a normal distribution.
