About the Course

Whether being used to customize advertising to millions of website visitors or streamline inventory ordering at a small restaurant, data is becoming more integral to success. Too often, we’re not sure how use data to find answers to the questions that will make us more successful in what we do. In this course, you will discover what data is and think about what questions you have that can be answered by the data – even if you’ve never thought about data before. Based on existing data, you will learn to develop a research question, describe the variables and their relationships, calculate basic statistics, and present your results clearly. By the end of the course, you will be able to use powerful data analysis tools – either SAS or Python – to manage and visualize your data, including how to deal with missing data, variable groups, and graphs. Throughout the course, you will share your progress with others to gain valuable feedback, while also learning how your peers use data to answer their own questions....

This course covers the basic data management and visualization using SAS and Python. I like the simplicity and straightforwardness of the contents. Will continue to explore this specialization.

The early videos in this course are well-done. I have studied this material before, and they provided a valuable "refresher" for me. The later videos attempt to cover too much ground, too quickly. The cross-disciplinary approach contributes to the feeling of confusion. I had also hoped that the data sets provided would be suitable for completing the course assignments. This was not the case, however. The OOL contains variables with many missing responses, and large numbers of response categories; the video examples are for categorical variables with two response categories The final week of the course frustrating, and I was unable to complete the assignment with the information provided.

This course is a great introduction to data management, SAS, and python. The videos and reading materials were very helpful and provided all the tools and strategies necessary to complete the assignments. The only reason I did not give the course a 5 start rating is due to the peer evaluation system. There was essentially no critical feedback provided throughout the course from peers. Most of the assignments I was asked to grade were spam or dead links. It was helpful to review the assignments of other students who submitted legitimate work, but these were very far and few between - maybe 4 out of the 15 assignments was asked to grade were submitted by real people.

There is a lot of self-teaching with these courses because there are no professors present to reach out to with questions. In addition, the course staff do not always respond promptly nor are they fully knowledgeable about all aspects of error messages that may arise out of coding. At times the code that were provided in the lecture videos were out of date and a lot of time was spent on googling to find the updated code. This is definitely not a beginner coder course and I do not recommend it to anyone who has not coded before.
