The ability to understand and apply Business Statistics is becoming increasingly important in the industry. A good understanding of Business Statistics is a requirement to make correct and relevant interpretations of data. Lack of knowledge could lead to erroneous decisions which could potentially have negative consequences for a firm. This course is designed to introduce you to Business Statistics. We begin with the notion of descriptive statistics, which is summarizing data using a few numbers. Different categories of descriptive measures are introduced and discussed along with the Excel functions to calculate them. The notion of probability or uncertainty is introduced along with the concept of a sample and population data using relevant business examples. This leads us to various statistical distributions along with their Excel functions which are then used to model or approximate business processes. You get to apply these descriptive measures of data and various statistical distributions using easy-to-follow Excel based examples which are demonstrated throughout the course.
To successfully complete course assignments, students must have access to Microsoft Excel.

This was a really enjoyable course, but challenging too. I struggled a bit with the final assignment, but nailed it in the end. My statistical knowledge base has indeed been enhanced by this course.

As a beginner, I found the course to be extremely useful and very clear. The professor guides you through each step in all his lessons, in a way that makes the course accessible even to a complete beginner. Although the lessons are relatively short, you are given the opportunity to learn a whole set of new skills, that can be surely useful across different jobs.

Only negative point: I would have liked more tests and exercises!

I took this as part of the specialization, so this review applies to the whole 5-course specialization. The files and PowerPoint slides were well-done; for example, unlike some other Excel courses I've taken on Coursera, the PowerPoint slides are explanatory and clear, the text is big enough to be able to take screenshots of for note-taking purposes, and the quiz and test questions are clearly worded. Sharad also is a very good lecturer- engaging and doesn't rush through things; rather, he reminds you of things throughout the course, rather than just mentioning them once and then never explaining it again and assuming you remember it.

A truly fascinating course. Keep in mind, this is an introductory course, and it is very useful for either refreshing your memory, or teach something useful and practical.

•25 sept. 2020

The type of final assignment questions and quizzes you all put are very difficult to understand and also it doesn't include in the lecture so whenever I give the final test my heart beats because after the quiz I get completely confused, also I feel that some of the options which you have given as correct answer are not what I believe. So, kindly please work on it as the purpose of taking a course is not to get confused but to be interesting and to learn more.

Excellent Course that simplifies the explanation of statistical concepts such as probability distribution for continuous and discrete variables and their business applications in the real world. The course is very well designed, well explained, and avoids theoretical details to the benefit of the focus on the statistical business application. Excel is a spreadsheeting tool that is readily available in (almost) all business environments and many people can leverage their investment on it by learning how to do statistical analysis using it before going to more sophisticated techniques after.

Truly wonderful course. The explanation of complex terms was done extremely meaningfully, in clear and simple to understand terms, many real world and practical examples were provided to drive the concepts home, and the exercises were challenging. Care was taken to not let the subject matter become too complex or abstract. I absolutely loved the little recaps and the sharing of handy tips and commands on Excel for immediate practical exploration.

Prof Borle's voice was crisp, loud and easy to follow, which to me was crucial.

All in all, an exceptional experience of learning. Thank you!

Improve assessment to be more learning oriented...many questions in the quiz of week 3 have no clarity and can result into several interpretations by learners...otherwise great course.

Some quiz questions can be confusing and not all assumptions are given. Read carefully and check the forum for people with similar questions.

I enjoyed this course very much. It covered a lot of useful topics to help you understand and apply statistical analysis methods. Professor Borle obviously put a lot of thought into the planning of this course, as the order of topics presented built on prior knowledge, and as usual were presented in a very clear and concise way. I would have liked additional depth and practice on the discreet distributions presented near the end of this course, but that is something I can do on my own time as well. I can't wait to start the next course in this specialization!

Truly a great course. Explains things slowly and clearly, provides practice problems to practice what you learn in the videos, and when you don't get or understand a question on the quiz the forum is helpful to help you UNDERSTAND an issue you're having.

The only thing I would tweak is not telling what function to use in the questions - instead, putting it in a helpful note if the student chooses to use it. What I've been doing, since I want to see if I understand when to use what function, is try and skip over them.

Fantastic course.

The instructor is very good. While he has an accent, he isn't hard to understand (and you can rewind if you do miss something :)) This course went step-by-step and explained everything clearly, with examples. The final quiz was just hard enough to know that you understood the material, but not so hard that you couldn't complete it. There were a couple of questions I had trouble with and I went out on the discussion forum to get help on them. (All of them were already out there so lots of people had trouble with them!)

All the important statistical concepts have been summarized in this course. The learners will be able to apply the concepts in real life scenarios easily using excel. Statistical distributions are really powerful and they are made really easy to use in excel by the Professor. Many thanks to him for clearing the concepts we have been hearing for a long time but never knew that they are really that much important in our daily lives

One of the best courses It has been my pleasure to complete! And by pleasure, I mean I really enjoyed the learning process. Nicely articulated through video lectures and handouts (for future reference), this course makes seemingly abstract concepts very clear and easy to comprehend. Lays the groundwork for hitherto unthinkable applications in a vast array of business scenarios. The quizzes reinforce the learning through videos.

It's a great course. There is no doubt that learning and using statistics can be challenging. It makes you think outside the box. And, learning the correct termination and how it is used is paramount. I would recommend it to others. In addition, I am not a big fan of study groups, but I can understand why many math majors join one. It gives you a chance to explore you logic and though process with others.

Even though this is an online course, one of the few issues that will be encountered is that questions during the course will not be entertained. Though since I have basic knowledge on the topic, the course was easy to follow and the general idea is provided well during the course. Most questions are addressed during the course thus, having a complete package and listening will be sufficient.

par Randha S

•21 oct. 2020

Thank you for this course! I was able to brush up on statistics learnt in higher school and learn to actually apply them in daily businesses of life. The only thing I'd want improvement is when giving graded tests and a question keeps going wrong, you get stuck. If better feedbacks are given, it would be easier and much more helpful. Otherwise great course!

This is a very practical course for those with limited or no knowledge of business statistics, full of real-world applications and opportunities to practice. As a communicator who does not have much of a business or statistical background, I've found this course to provide an excellent foundation and understand of such important business processes.

I really like how the professor structures the class and videos. The videos are all very concise yet full of useful information, and the explanations are always clear and easy to follow. The examples used in videos are well selected and extremely helpful to understand how statistical concepts can be applied to solving real life problems.

The content load is just right for beginnners (which is my case). I feel I learned more from this course than from my Stats class in college, at least the concepts are clearer, even though I was using for the past decade some of the calculations taught in this course, but now I feel more confident in knowing what I'm doing.
