课程概述

Survey data sets are often deceptively complex because surveys collect a wide variety of data covering a wide variety of topics and experiences. To further the complexity of survey data, the respondents answering the questions come from a wide variety of backgrounds and stages in their customer journey. It is reasonable that it would be a challenge to boil down survey data into actionable insights because it can be deceptively complex. With large sets of data, Principal Component Analysis or PCA is a useful tool that reduces and transforms variables to a leaner form that allows for a speedier analysis. In this project you will gain hands-on experience with the principles of Principal Component Analysis using survey data. To do this you will work in the free-to-use spreadsheet software Google Sheets. By the end of this project, you will be able to confidently apply Principal Component Analysis concepts to transform large sets of variables into a leaner set of data that still contains the most relevant information. 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....

Deeper knowledge on PCA should be introduced, more complex project or case should be given. Learning PCA through Excel is never enough.

Course was very helpful. However it would be better if analysis on more number of variables could be conducted

The course was simpler than I imagined. However, it was interesting to learn about the tool and its possible uses.

D​on't waste your time on this course. No theory of PCA, no real practise! Just functions "correl" and "average" in google sheets used. And have a look at PCA in https://biit.cs.ut.ee/clustvis/ without any explanation why, what, how... explore yourself. LOL... Epic....
