Descriptive Statistics

Question 21

is concerned with higher degree of critical judgment and advanced mathematical modes such as using the different statistical tools both the parametric and nonparametric tests. This is concerned with the analysis and interpretation of data in order to draw conclusion and generalization from organized data. This also includes the testing of the significant relationship between the dependent and the independent variables as well as the significant differences between and among independent samples.
