Overall, this is a good introductory course. I think it is very good for people that are starting with Excel or statistics, and business analysis.

However, I removed one star considering my personal experience. At times I feel it slow, maybe I made the wrong decision, because I already have some background and I was looking to refresh it and have more practical knowledge. I don't find it very challenging, but will complete the specialization for the certificate and to see the remaining 2 courses in it.

overall good experience but quiz of week 2 was planned terribly many students faced problem because of rounding error and question suggested to use goalseek or solver but neither of them were taught in this course nor in other course of this specialization and please fix rounding error problems

This course was very different from the other data analysis courses. it really shows one how to compare data points in the same sample/population.

very interesting and many thanks to the prof, he made it easy to understand! the examples here as there were alot really helped!! thank you!

This was a really interesting course. Some of the video lectures were longer than usual however, the content and the way it was taught kept it interesting. I'd definitely recommend this course to friends.

It's great/ but sometimes I find it a little confusing when so many new concepts come to me. Better take notes while you are having this course^-^

Good explanations in videos, however sometimes there are to many repititions. As in previous courses, explanations after quizzes are missing.

A good overview of Z and T tests. Would have liked to see ANOVA or the F statistic as well to refresh myself on those statistics.

Great way to learn useful knowledge from home and in a easy and fast way. Very helpful when you usually work with data analysis.

useful course. It can add some more details and differentiation between T.INV and T.INV.TWO functions used in excel.

Good intro to hypothesis testing using excel for business problems. Lectures are easy to follow - but take notes!

Loved the course! The structure and explanation throughout is brilliant for a newbie.

The course helped in strengthening my basics of hypothesis testing.

It needs to show the correct answers when you do wrong in the tests

Excellent course to refresh your knowledge about inference

There are many same slides in the file!

Really enjoy the leaning. Thank you.

too easy compared to part 1 &2

Brilliant course!!

more application

Good course

OK

I won't be recommending this course if you don't have an MS Excel subscription because you will be needing some premium MS Excel tools to understand and cover-up assessments (which MS Excel free version doesn't have). The instructor is good and the videos are informative but the slides in the video are not enough for notes. Make sure you make your own notes. Good luck :)

Week 3 and 4 are simpler; but week 1 and 2 took a lot of external references to understand.

Question and Answers are not properly structured and it really increases the doubt for the candidate. Really not satisfied with the final assignments where in some cases proper explanation is not given.
