Analytical Solutions to Common Healthcare Problems
In this course, we’re going to go over analytical solutions to common healthcare problems. I will review these business problems and you’ll build out various data structures to organize your data. We’ll then explore ways to group data and categorize medical codes into analytical categories. You will then be able to extract, transform, and load data into data structures required for solving medical problems and be able to also harmonize data from multiple sources. Finally, you will create a data dictionary to communicate the source and value of data. Creating these artifacts of data processes is a key skill when working with healthcare data.
Manipulating Data with SQL
In this course you will learn to write the SQL code to manipulate the data in a relational database table. You’ll begin by populating the table with data. Since a database and its tables are designed and built to be repositories of data, getting the data into the tables is a critical activity in the building of a working database. When building a new home, the real test of your design comes when the furniture and family move in. It’s much the same with designing and building database tables—the real test comes when you load data into the tables and begin to use it. As you work through and complete hands-on tasks, you’ll become familiar with SQLiteStudio, the database management system used in the course. You’ll experience first-hand the impact data types and constraints have on manipulating table data. For example, as you enter new data into a table, you’ll appreciate the extra protection provided by the primary key constraint. It will not let you insert two rows into a table that are exactly alike. In addition to adding data to the tables, you’ll write the SQL code used to modify existing data values and to delete rows of data. Managing and manipulating data are SQL’s primary purposes, and SQL coding will be a powerful addition to your tool set. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Your new skills will help you efficiently manipulate data and operate with formulas that can help make more efficient management decisions in the future.
Data Visualization Capstone
Data visualization is a critical skill for anyone that routinely using quantitative data in his or her work - which is to say that data visualization is a tool that almost every worker needs today. One of the critical tools for data visualization today is the R statistical programming language. Especially in conjunction with the tidyverse software packages, R has become an extremely powerful and flexible platform for making figures, tables, and reproducible reports. However, R can be intimidating for first time users, and there are so many resources online that it can be difficult to sort through without guidance. This is the final course in the Specialization "Data Visualization and Dashboarding in R." Learners in this course will enter with a well-developed set of skills making a wide variety of visualizations in R. The focus on this course will applying those skills to a unique project, drawing on publicly available data to tell a compelling story using the data visualization toolkit assembled in the previous courses.

Artificial Intelligence Algorithms Models and Limitations
We live in an age increasingly dominated by algorithms. As machine learning models begin making important decisions based on massive datasets, we need to be aware of their limitations in the real world. Whether it's making loan decisions or re-routing traffic, machine learning models need to accurately reflect our shared values. In this course, we will explore the rise of algorithms, from the most basic to the fully-autonomous, and discuss how to make them more ethically sound.
