This report presents a statistical analysis of Singapore's life satisfaction levels, comparing data from 2002 and 2012. The analysis encompasses descriptive statistics, including mean, median, mode, standard deviation, and variance, to summarize the datasets. Confidence intervals are calculated to assess the uncertainty associated with the sample means, and hypothesis testing is performed to determine if there is a statistically significant difference in life satisfaction between the two years. The report also includes data visualization and a discussion of the data's characteristics, such as skewness and range, to provide a comprehensive understanding of the trends. The findings suggest a decline in life satisfaction among Singaporeans during the observed period, attributed to various factors. The report concludes with recommendations for future data analysis and highlights the importance of statistical methods in drawing meaningful conclusions from survey data.
