課程概述

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 is a great course for beginners. The course instructors have arranged the course at a very comfortable pace and this is a great beginning point for anyone who wants to learn SAS or Python.

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.

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 At times the code that were provided in the lecture videos were out of date and a lot of time was spent on googling to find the updated code.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.

This course is very simplistic, but interesting. I was able to complete the first 3 modules within a week, however I am somewhat skilled in this area. I was looking for something more difficult. However, my main goal was learning these techniques in python. It was frustrating that it took so long until we actually produced graphs (I don't like just looking at tables). However, all in all, it was useful and interesting -- I really like the applications-based approach. You get to analyze data about whatever YOU are interested in!

The course is great otherwise, however the certificate of this course just completed 'Data Management and Visualization' with no mention about the skills learnt or the grade attained.

Primary reason I enrolled to the course was to list 'SAS' (basic) as a skill in my resume, however the certificate does not mention anything about SAS. If at least the certificate said completed 'Data Management and Visualization with SAS', it would be a good value for money.

I strongly recommend Coursera should look into this. Thanks!
