課程概述

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.

Very confusing stuff, need better clarification in course description and the way the material is transmitted to the student need to be reconsidered

But very well made and interesting.

El curso no ense;a cosas prácticas en el análisis de la data. Además el enfoque es muy financiero, tomando en cuenta que no existe solamente el sector privado sino también el sector

Not quite the excel actually relevant to industrial requirements. had to leave the course mid way.

There are better Excel DA courses out there. Concept presentation was good though.

Very little to do with Excel, mostly focused on statistics with brief overviews of how things could be done within Excel, but very little focus on actual Excel use and knowledge.

The lectures are poorly delivered. The quizzes are ambiguous. The files available for download are erroneous. It seemed the professor was not paid for this course. Stay Away!!

I wish there were more quizes after each video to memorize the formulas and get a hold of them.

For the begginers this course is way too difficult to comprehend on their own.

Too much material, that moved too fast. Wasn't opportunity for enough feedback and explanation. I say this as someone who went to Duke and has taken similar classes at Duke!

The content of the course was good.

However, I did not like the presentation of the material, moreover such a topic would need to be covered by a longer duration course.

This is a high level course and the beginners cant adapt easily with the probability and statistics terms used.

A better way of teaching could have been used.

The title is misleading .

This course has a little to do with excel , you could get some mathematical information but I do not think you will master anything

The transition is from easy to advanced. It gets really confusing, not sure if it's just me. I am not following the lessons anymore so I left the course.

I found Week 2: Binary Classification really confusing. It was just not clear. Specifics were not given. Definitions were not given. Poorly instructed.

Course material is too heavy for a beginner. I would not be able to continue. For a new comer it is an heavy stuff taught like a brushing up course.

Significant difference between the material covered during the class period and the examinations. It could be improved considerably. Thank you.

Great idea. Unfortunately, the course is young and there were too many bugs to get past Week 2. Hopefully these will be finished my next session

Very confusing. I passed this course but I felt like I didn't learn too much. I think they should include prerequisite for this course.

Was quite advanced and the topics weren't explained as well as I expected them to be .Overall, the course was below average.

I found much of this material wasn't as applicable to excel analysis as hoped and didn't cover many of the analysis tools

Este curso tiene mal el titulo, no trata sobre excel en absoluto, sino mas bien es un curso sobre matemáticas.

I'm here learning Excel skills, but this course, especially week 2, does not teach Excel skills.

This course is more advanced than a college stats class with not much explanation. Be prepared.
