The book introduces the basics of data collection and presentation. It introduces measures of central tendency such as mean, median, and mode. The principles of probability are explored, covering random events and distributions. It then explores the principles of probability, discussing random events and different distributions, which helps students understand the uncertainty inherent in economic analysis. Descriptive statistics are also emphasized, as they allow data sets to be summarized and described using graphs and measures of dispersion, making it easier to interpret the information. The book also covers statistical inference methods, such as hypothesis testing and confidence intervals, which allow meaningful conclusions to be drawn from samples. In addition, the book introduces analysis of variance (ANOVA) as a valuable tool for comparing multiple groups, which helps determine whether there are significant differences between them.
