Statistics Master's Degree, Data Analysis, Machine Learning

Updated: Jun 13

I am applying to the Master’s Degree Program in Statistics at XXXX University. I hope to make research in Statistics the focus of my career because I especially enjoy modeling real-world situations with math and interpreting data to make rational decisions that serve to enhance efficiency. I want to be a data scientist at the service of the business community because I very much enjoy how data drives decision-making. I appreciate the certainty and honesty of data, which helps compensate, as I see it, for the uncertainty associated with human behavior. My undergraduate projects, experience as a volunteer, and my great passion for this field confirmed this interest.

Data analysis is attractive because it is similar to an adventure, where hidden treasure maps are waitingconfidential for me to discover, leading to the ultimate treasure. I adore Statistics because it is a powerful tool that enables me to dig deeper in search of confidential information and patterns. One of the projects I have conducted was establishing a regression model to predict SAT scores for 50 states in the U.S. I found that Alaska has the highest leverage because it has the highest state values for income and expenditures. Furthermore, because of the tremendous importance of the studentized residual and cook’s distance, Alaska is very different from the other states. Therefore, I considered Alaska an outlier and removed it from the data set. However, even though Alaska has been removed, the plot for residuals versus leverage indicates that the states Mississippi, Louisiana, and Oregon are also outliers. These states do not have any single variable that stands out but has a unique combination. The project also involves Mallow’s Cp and adjusted R square to determine the best model. However, these methods only reveal a corner of the data set depending on the questions. I want to be equipped with a more advanced capacity for exploration.

I see Statistics as a vehicle for making a human contribution – and to as many people as possible simultaneously. I have been volunteering with MathCEO as a data analyst. My team was assigned to investigate whether our program influenced students' math test performance. We wanted to establish a model to predict their scores with a given norm and compare them with their actual scores. However, I realized the limitations of my current statistics knowledge and data analysis skills to solve these problems; both the linear regression model and the interpolation methods I have learned from the numerical analysis courses were excessively extrapolated. Even though the issue has been resolved by the conditional growth index provided by the test institution, it would have been more effective and efficient if I could analyze such a large amount of semi-structured or unstructured data with my current knowledge of statistics and data science.

Since finishing my undergraduate studies, I have continued to mature professionally and prepare myself for graduate school. I have learned SQL and became certified in Google analytics in this area. I am also taking an online course at Udemy on machine learning data analysis. These experiences have enhanced my interest in data mining and machine learning, especially concerning their relevance to Statistics. I look forward to studying in your program: the core theoretical courses, Probability Theory, Statistical Methods and Research, Big Data, and High-Performance Statistical Computing. I find my most complete fulfillment in helping others with the analytical skills I could gain throughout the program. I am convinced that the most significant contribution I can make to my society is in the area of Statistics.

If admitted to the program, it would be a special honor to study under Dr. XXXX, an expert in statistical programming, who would help me appreciate how much technology changes our life more fully. Since my ultimate goal is education, Dr. XXXX is also most qualified in the area of statistical education to represent my ideal mentor.

I am committed to success in the Master’s Program in Statistics at the University of California, XXXX. While I love business and profoundly enjoy helping them prosper, I will always hold a fondness in my heart for academic applications of data science. I may well decide to make this aspect of my studies the centerpiece of my career. Upon obtaining my master’s degree, I want to use my knowledge to help organizations and cities become more prepared and effective, eventually devoting myself entirely to education or educational analysis.

Thank you for considering my application to Statistics at the University of California, XXXX.
