Workflow of Data Analysis
A 3-Day Livestream Seminar Taught by Bianca Manago, Ph.D.
Statistical analyses are only as good as the data that go into them. This is why the majority of time on any data analysis project should be spent, not on conducting the analyses (i.e., actually running the model), but instead on the steps needed to prepare the data for analysis. There are dozens of decisions that go into data management. If not properly documented or considered, those decisions can produce erroneous results or preclude replication.
This seminar is designed to teach researchers how to prepare data for analysis in a way that is both accurate and replicable. By following these principles, your data analytic projects will be both well-planned and executed. The scope of the seminar ranges from such broad topics as developing research plans to the detailed minutia of planning variable names.
Starting October 13, we are offering this seminar as a 3-day synchronous*, livestream workshop held via the free video-conferencing software Zoom. Each day will consist of two lecture sessions which include hands-on exercises, separated by a 1-hour break. You are encouraged to join the lecture live, but will have the opportunity to view the recorded session later in the day if you are unable to attend at the scheduled time.
*We understand that finding time to participate in livestream courses can be difficult. If you prefer, you may take all or part of the course asynchronously. The video recordings will be made available within 24 hours of each session and will be accessible for four weeks after the seminar, meaning that you will get all of the class content and discussions even if you cannot participate synchronously.
Closed captioning is available for all live and recorded sessions.
More Details About the Course Content
This seminar is for researchers who are trying to establish or improve their workflow. Participants do not need to be expert programmers; this seminar should be accessible to very novice Stata users, while still being useful to more advanced users. Lessons from this seminar balance ease of use with proper functioning, introducing researchers to useful tools, e.g., dual-pane browsers, macro programs, plain text editors, and GitHub. For those who are already familiar with these tools, this seminar will teach you how to optimize them. Lessons from this seminar should make conducting research less painful, more efficient, more accurate, and reproducible.
This is a hands-on seminar with ample opportunities to plan and practice your workflow.
Some highlights include:
- Planning (analyses, sensitivity analyses, variable construction, etc.)
- Directory structure
- Data preservation
- Dual workflow (separating data management and analyses)
- Writing robust script files
- Using log files
- Variable naming
- Value labeling
- Reproducibility and replication
- Examining data
The empirical examples and exercises in this course will emphasize Stata. To fully benefit from the course, you should use your own computer with a recent version of Stata installed. You are encouraged to use Stata version 17, but earlier versions should also work for most exercises. You should have familiarity with the Stata programming language.
For those who prefer R, equivalent R code will be provided on request.
If you’d like to take this course but are concerned that you don’t know enough Stata, we recommend following along with a “getting started” video like the one here before the seminar begins.

Reviews of Workflow of Data Analysis
“This should be required learning for all researchers. The course covers the principles/rationale for having good workflow as well as concrete steps you can do right away to improve your own workflow. I was able to immediately implement steps that I know will make me a better researcher. I also have the resources I need to tackle larger changes to my workflow in the coming weeks. It’s been 5 years since I completed my PhD and I wish I had taken this course in my first year. I left this course feeling excited and empowered.”
Marta Mulawa, Duke University
“The presentation of the topics, time management, and the content of the course were all excellent.”
Mbaraka Amuri, CDC
“Great class! Bianca Manago is a superb teacher; positive, enthusiastic, extremely knowledgeable, clear, and responsive and helpful to students. I gained extremely valuable insights, principles, tips, and practical strategies that will improve the quality, reproducibility, and replicability of all my research.”
Ken Coburn, Health Quality Partners (HQP)
“Bianca was a great, knowledgeable entertaining teacher. She really made what could have been very dry material seem exciting. The knowledge I gained in this course will revolutionize the way I approach my research projects.”
Laura Prichett, Johns Hopkins
“This was a very informative seminar. I would suggest if for all data managers, analysts, and study team members. There are many practices suggested that would beneficial to a study team.”
Angela Green, Johns Hopkins University
