my work

In this document I demonstrated my expertise in data wrangling and statistical analysis. The first step I carried out data management/manipulation this to ensure that the data is free from errors. Second step I performed Exploratory data analysis in both categorical and continuous variables where in categorical variables I only bar graphs and tabless in form of frequencies and percentages. On the other, I explore continuous variables with differents chart including histogram this check the mean distribution of the continuous variables , box plots to check the outliers and median distribution and again I correlation heatmap to check the correlation between the continuous variables. Thereafter, I performed some regression analysis e.g linear regression, logistics and cox regression as well as hypothesis testing e.g One sample t test and two samples t test . All these is to demonstrate my skills in data science and statistics.
