About the Course

This course introduces students to data and statistics. By the end of the course, students should be able to interpret descriptive statistics, causal analyses and visualizations to draw meaningful insights. The course first introduces a framework for thinking about the various purposes of statistical analysis. We’ll talk about how analysts use data for descriptive, causal and predictive inference. We’ll then cover how to develop a research study for causal analysis, compute and interpret descriptive statistics and design effective visualizations. The course will help you to become a thoughtful and critical consumer of analytics. If you are in a field that increasingly relies on data-driven decision making, but you feel unequipped to interpret and evaluate data, this course will help you develop these fundamental tools of data literacy....

Very well! The two courses that I studied for this Specialization have really been a good reason to continue.

The voice of Mrs. Instructor and the explanation of each topic have been effective in teaching this subject.

Only many more exercises and examples are missing to experience our applications for ourselves. I hope more practice in the updates of the courses, if they exist.

Thank you!

The quiz and test questions were really well thought out and required application of the knowledge presented in the course. They re-enforced the learning. The course definitely help shaped my view of Data Literacy. I like the support articles. Great sources for reference and further analysis. Thanks 100% enjoyed the class

I came in trying to get a better explanation of statistical concepts and I was not disappointed. This course demystifies statistics by providing clear and simple explanations. The use of relevant examples makes anyone be interested in using statistics to get a better view of the world.

This is a very well done course that does an excellent job at explaining concepts of scientific theory, basic data analysis, and visualization. These are concepts that I would absolutely use to introduce the subject to others in my organization.

This course provides a broad introduction to statistical methods and visualisations. Whilst there is not obligatory practical work to do, the course does a good job of ensuring that you understand the fundamentals. Some of the week-end quiz questions are poorly formed (e.g. gives you two answers, both of which are correct, but only one of which counts as right in the quiz) - that's my only criticism.

A nice introduction. The use of the Introductory Statistics textbook was good and I've earmarked it for future reference; a couple of the blog reading choices about graph types could be updated. Looking forward to the next course in this specialization.

An excellent introductory course for data understanding and analysis, I would advice to simplify the related readings to be more clear.

Some of the quiz questions feel a bit unfair. Answers that are "Accurate, but..." do not feel appropriate for these kinds of lessons.

This is a very clearly presented and well-prepared course. Some of the readings are much too advanced compared to the content of the videos and the quizzes. The course could use a little character.
