Objectives of the course :

• The course aims to:
• Introduce students to some concepts related to statistics, statistical methods, types of statistics, frequency distributions, and data representation.
• Train students on calculating measures of central tendency and identifying the differences and relationships between them, calculating measures of dispersion, understanding the relationship between them and measures of central tendency, determining the shape of the distribution curve (normal, positive skew, negative skew), and utilizing the coefficient of variation and the relative coefficient of variation.
• Training the student on applying some parametric and non-parametric statistical methods such as the “t”-test, Mann-Whitney test, Wilcoxon test, and correlation coefficients, the conditions for using each, and how to interpret the results.
