This report presents a statistical analysis of the gender wage gap, examining income disparities between men and women across various occupations. The study utilizes two datasets: one from the Australian Tax Office and another collected through convenience sampling. Descriptive statistics, including graphical representations and numerical summaries, reveal differences in gender representation across different professions and a clear wage gap, with women overrepresented in lower salary brackets. Inferential statistics, such as confidence intervals and t-tests, are used to analyze the data further. The results indicate that there is a significant difference in average income between males and females, and the study finds a significant difference in the average income of males and females. The report concludes that the wage gap is influenced by the distribution of genders in high-paying occupations and recommends further research to understand wage disparities in female-dominated professions. The study uses t-test analysis and hypothesis testing to determine the gender gap in the average income and finds that the difference in the average income of males and females is not significant.
