デューク大学(Duke University) による Mastering Data Analysis in Excel の受講者のレビューおよびフィードバック



Important: The focus of this course is on math - specifically, data-analysis concepts and methods - not on Excel for its own sake. We use Excel to do our calculations, and all math formulas are given as Excel Spreadsheets, but we do not attempt to cover Excel Macros, Visual Basic, Pivot Tables, or other intermediate-to-advanced Excel functionality. This course will prepare you to design and implement realistic predictive models based on data. In the Final Project (module 6) you will assume the role of a business data analyst for a bank, and develop two different predictive models to determine which applicants for credit cards should be accepted and which rejected. Your first model will focus on minimizing default risk, and your second on maximizing bank profits. The two models should demonstrate to you in a practical, hands-on way the idea that your choice of business metric drives your choice of an optimal model. The second big idea this course seeks to demonstrate is that your data-analysis results cannot and should not aim to eliminate all uncertainty. Your role as a data-analyst is to reduce uncertainty for decision-makers by a financially valuable increment, while quantifying how much uncertainty remains. You will learn to calculate and apply to real-world examples the most important uncertainty measures used in business, including classification error rates, entropy of information, and confidence intervals for linear regression. All the data you need is provided within the course, all assignments are designed to be done in MS Excel, and you will learn enough Excel to complete all assignments. The course will give you enough practice with Excel to become fluent in its most commonly used business functions, and you’ll be ready to learn any other Excel functionality you might need in the future (module 1). The course does not cover Visual Basic or Pivot Tables and you will not need them to complete the assignments. All advanced concepts are demonstrated in individual Excel spreadsheet templates that you can use to answer relevant questions. You will emerge with substantial vocabulary and practical knowledge of how to apply business data analysis methods based on binary classification (module 2), information theory and entropy measures (module 3), and linear regression (module 4 and 5), all using no software tools more complex than Excel....



The course deserves a 5-star rating because: (1) content is relevant, (2) the professor is concise and possesses great teaching skills, and (3) the learning modules are applicable to daily problems.


The course was excellent. A little difficult and overwhelming at times but as long as you stayed the course the professors gave you every opportunity to succeed. Thank you for your time professor.

The whole course has very little about excel, rather about aweful a lot of data models. The course title is very misleading.

by Despoina E


It's quite interesting, but definitely not a beginners one. I'm put off quite a bit by the exclusively financial examples

by Milan M


after the second week I droped this course...I thought it will include excel and economics knowledge but was very wrong..

by Avulapati N


The course content is great and the instructor also explained concepts well!

The course assignments are outdated tough.

The later part of the sessions lacks practical applicability and it is more abstract, that I find difficult to relate

by Rotimi


It's too advanced for people with no experience in statistics and sometimes too abstract to relate with

by B. A N


The course was informative but needed more examples to understand the concepts like the final example.

by Camilo E S C


Really bored... now, I want to change and they charge me more for that. what a bad service, just money

by Izayas R J


The importance of this course is huge. However, I did miss better explanation from some topics...

by Santiago Y A


It's more statistics than Excel itself, wich is good but I think the name doesn't fit to it

by Stephanie H


this course is to some extent too difficult for me, It is not easy for me to understand.



un poco complicado para mi creo q falta informacion en que apoyarme para los ejercicios

by 王伟


it is too complicated for me this courese, not very useful for daily work. but anyway i

by Jared V


This course was over my head academically and I was able to glean very little from it.

by Chris H


They have a lot of good material. It will probably be better the second time around.

by Jongah K


not recommend if you want to learn about Excel. More fore stat/analytics in general

by Qian W


could have lecture more.... the videos talks little about the spreadsheet provided

by Eunice H


it seems like there need to be some prerequisities to this class, like finance.

by Samhita A


It was a bit too fast and there is a lot of math formulas than I expected

by César R


The order and content of the lessons wasn't planned with sufficient care.

by Sebastiaan B


The second test should be compulsory for also the non-paying students!

by Steven T


The content was very useful but I felt that instruction was lacking

by demehin I


still needs a better way of explaining the diversity of the course

by Luke R


Good Course, but final project asks a lot for what this course is

by steven u


Good intro and fundamentals, but focuses far too much on finance.
