The Probability and Statistical Data Analysis course was one of the most exciting course this semester. In this course we had to do two projects. In project-1 we worked with data type, box plot, bar chart , histogram and more. Most of these I was already a little bit familiar with. This project was exciting as we needed to gather our own data via questionnaire but Project-2 was a lot different.
In project-2 we worked with hypothesis testing, correlation, regression and chi square test of independence. I was not familiar with these topics at all so I was a bit nervous. But, with the help of our wonderful course lecturer Dr. Sharin all these concepts became clear for me so I started working on the project. At first I needed to find a dataset with which me and my team. It took a lot of time to find a dataset with which we can work with. In the end I picked a dataset related to "In Hospital Mortality Rate" of the patient in the ICU. The next step was to perform the tests with this data set but it had more than 1100 data so I had to process it and take it down to about 400. We worked with Age, gender, Diabetes, Systolic blood pressure, Diastolic blood pressure and Respiratory rate. We used R Script to perform the hypothesis 1 sample test, Regression, Correlation and chi square test of independency. We found out that the mean age of the patient in the ICU was above 70 years old, the relationship between the heart rate and systolic blood pressure was a weak negative relationship and we also found that In general men don’t have better chances of getting affected by diabetes than females.
To conclude this project was exciting, fun and very useful for us as we learned to use the topics learned at this course in real life. In the future I can use these analysis techniques to prove my statement or hypothesis in real life scenarios. Also it definitely helped me gain a new skill which was R scripts language. It was really enjoyable to work with this programming language. Hopefully I will get work on a project like this again in the future .
