# PIC Math Workshops on Data Science

### About the Workshops

The PIC Math Workshops on Data Science were aimed at mathematics and statistics faculty members with little or no experience in data science. The workshops were held on the campus of Brigham Young University in Provo, Utah from May 29-June 2, 2017 and from June 18- 22, 2019. The workshops were supported by PIC Math which is a program of the MAA.

In these hands-on workshops, attendees were:

• introduced to the field of data science/statistical learning/machine learning;
• given an overview of techniques and software used to solve data science problems; and
• taught how to guide undergraduate students working on real world data science problems

### Data Science

 In this PIC Math Solving Real World Problems video, Dr. Jonathan Adler talks about his career path and how he used text analytics to help an online company distinguish between its business customers and private customers.

Data Science is the process of examining data sets in order to draw insights and conclusions about the information they contain. Many PIC Math undergraduate research teams have worked on data analytics and science problems. Here are some examples:

1. Manhattan, New York: Students from Manhattan College received data from the animal shelter on abandoned pets during the period from 2012 to 2015. The students analyzed the data and identified trends about dogs and cats abandonment rates.

2. Kansas City, Missouri: Box Office Analyst is a consulting firm for the movie theater industry. The company uses survey data to help theater owners decide which movies to play in their theaters. Students from Rockhurst University used the survey data to build a mathematical model that would predict opening weekend revenues for new movies.

3. Youngstown, Ohio: The city has seen a dramatics decline in its city population and a shift in the location of the population over the past forty years. However, the police department was still using a division of the city into police beats that was created decades ago. Students from Youngstown State University received 2014 crime data from the police department, analyzed the data, and proposed two new models for more equitable divisions of the city into police beats. The police department adopted one of the proposed models.

The workshops included an overview of data science, a taste of Python, a morning of overfitting and training, a plethora of free data resources, machine learning, and getting our hands dirty working in groups on a real-world problem.
