Week-5

Today, our classmate Mahnoor delivered a presentation in which she shared her insights on the percentage of people shot in a particular county. She discussed patterns in the data, focusing on how these incidents have occurred continuously over a period of time. Her analysis provided valuable perspectives on trends and potential factors contributing to these occurrences.

I began experimenting with machine learning models to predict the likelihood of a suspect being armed. I used logistic regression and decision tree classifiers and evaluated their performance using accuracy and confusion matrices. I understood how feature selection and data balance affect model predictions. Although the accuracy wasn’t very high, the models gave interesting insights into which factors mattered most.

Week-4

Today, we explored various fundamental topics in statistics, including standard deviation and the standard normal distribution. Additionally, we engaged in a discussion on inference-based questions, particularly focusing on comparisons across different fields such as age, race, and other demographic factors. This discussion helped deepen our understanding of how statistical inferences can be applied to analyze and interpret data effectively.

Week-3

While analyzing the dataset, I came across several questions that could help me understand it better.

What is the racial and gender breakdown of individuals shot by police?

Are certain groups disproportionately affected?

What is the average age of individuals involved in police shootings?

Are younger or older individuals more frequently involved?

What percentage of the victims were unarmed versus armed?

What types of weapons were most commonly involved?
