BSAD 8700 - Business Analytics

Instructor: Dustin White, PhD

Email: drwhite@unomaha.edu

Course Description

This course is designed to help you learn about the most important topics and methods that make up modern data analytics. We will discuss how to use data tools to improve your understanding of business decisions, and how to communicate clearly with data analysts about the goals of your team, and conveying results from data analysis projects to managers. This course is intended to help you build a bridge between technical teams and management, providing value through an ability to communicate business needs to technical teams and technical results to managers who may not be familiar with analytics methods.

We will cover eight topics during this course. Lectures/videos will be relatively short. The rest of the time that you spend in this course will be a series of REQUIRED labs in which you will use data analytics to implement incremental class projects. The goal of this course is to improve your ability to take advantage of data analytics in your career. If there are things that we are not covering that you feel are critical, please bring them up to me so that I can help you with the topics you care most about!

Textbooks

The assignments for this class will be made up of reading assignments from two books:

  1. Predictive Analytics, by Eric Siegel (ISBN:978-1119145677)

  2. Data Science for Business by Foster Provost and Tom Fawcett (ISBN:978-1449361327).

For each topic, you will write a one to two page summary applying the readings to your job (or to your life or hobbies if you are a full-time student), and how they could be implemented by you or your team at work.

Course Structure

Topics 1-4 will cover the material needed for the first project in the course (which will be due after we begin topic 5), and topics 5-8 will correspond to the second semester project.

Topic 1

Introduction to Data Analytics – This week we will discuss what data analytics is and what it is not. Data analytics is kind of a hot thing right now, and we want to make sure that we understand some limitations of using data. Topics will include: defining data analytics, flaws in data, omitted variables, and asking the right questions. In lab, we will get acquainted with data by using Tableau software to visualize and get to know some interesting data.

Read PA: Intro and DSB: Ch. 1

Topic 2

SQL and Databases – This week we take a critical step in making use of very large datasets: we need to learn how to access small segments of them quickly, and to construct basic explanations of that data, so that we can understand what the data might be used for. I will walk you through what SQL is, and how to use it to query a database. In lab, we will use our time to find an interesting subset of a database for our first project, and construct summary statistics for that data.

Read PA: Ch. 1 and DSB: Ch. 2

Topic 3

Data Visualization – Now that we have done some basic work in both creating smaller, more tractable data, and in basic data visualization, we are ready to talk about the importance of visualizing data, and using that to inform our analysis. We will talk about good and bad visualizations, and how to tell the story of your data using visuals. In lab, we will prepare high-quality visualizations that we could use to present and explain important aspects of the data that we explored in Week 2.

Read PA: Ch. 2 and DSB: Ch. 3

Topic 4

Introduction to Regressions – After spending the past few weeks exploring our data, and getting our heads around the questions that we might want to ask of our data, we will talk about classical methods of data analysis. We will spend some time talking about what correlations and regressions are, and about when they are the best tools for the job. In lab, we will take our data, and explore the effects of variables that we choose on some outcome that we care about. We will be able to combine this information with our visualizations and summary statistics from previous weeks into a nice briefing for our “boss” about what we learned from our data, and why he/she should believe our discovery.

Read PA: Ch. 3 and DSB: Ch. 4

Topic 5

Classification and Supervised Learning – For the second half of the course, we will focus primarily on classification techniques. This week, we will discuss what classification is, and why it is so popular in data analytics. We will also define supervised and unsupervised learning, and look at an example of each. Lab this week will be focused on trying to visually classify individuals using plotting and other visualizations of our data.

Read PA: Ch. 4 and DSB: Ch. 5

Topic 6

Decision Trees – Decision trees are one of the simplest and most powerful analytic tools in use today. We will talk about what a decision tree is, what makes it different from a histogram classifier, how it is “grown”, and how it is “pruned” in order to come to the best tree for making out-of-sample classifications of observed data. Lab will consist of preparing data for use in decision tree algorithms, as well as training a decision tree in order evaluate its accuracy in out-of-sample predictions.

Read PA: Ch. 5 and DSB: Ch. 6

Topic 7

Ensemble Methods – Just like people, an individual algorithm might be biased. By combining many decision trees or other machine learning algorithms, we can come to a more accurate estimate based on the available data. We will discuss how ensemble methods work, their advantages, and their use in industry. In lab, we will generate random forests of decision trees in order to improve the accuracy of our predictions from last lab.

Read PA: Ch. 6 and DSB: Ch. 7

Topic 8

Data Maturity and Cutting Edge Models – The tools we have learned so far have been easy to apply, and they work in ways that are easy to visualize. More advanced techniques such as neural networks perform the same tasks, but can be applied to many more difficult problems such as natural language processing and image processing. We will go over the basic concepts of neural networks in class, and explore a simple neural net in lab in order to compare it to the other techniques we have learned.

Late Assignments/Quizzes

I will not accept late assignments or quizzes for any reason, including technical or internet issues. Remember that work can be done ahead of time if you think that you will be unable to complete an assignment during the week that it is due! Having access to a computer and internet connection are your responsibility when enrolling in an online course.

Course Goals

  1. Demonstrate understanding of the most important methods underlying modern data analytics
  2. Demonstrate the ability to use data tools to make business decisions
  3. Clearly communicate results from data analysis projects to a lay audience

Technology Problems?

Reach out immediately! Please note technical issues are not a reason for accepting late assignments.  Do not wait until the last minute to complete your assignments. 

How Can You Be Successful in this Course?

  1. Take your time to complete the readings, video modules, and projects. Waiting until the last minute to complete them is not recommended. I have taught this class often enough to know a last-minute project when I see one. 
  2. Be involved in discussion. It's not required, but it IS where you can learn more and discuss applications!

Students with Disabilities

Reasonable accommodations are provided for students who are registered with Disability Services and make their requests sufficiently in advance.
