課程概述

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. ________________________________________ WEEK 1 Module 1: Basic Data Descriptors In this module you will get to understand, calculate and interpret various descriptive or summary measures of data. These descriptive measures summarize and present data using a few numbers. Appropriate Excel functions to do these calculations are introduced and demonstrated. Topics covered include: • Categories of descriptive data • Measures of central tendency, the mean, median, mode, and their interpretations and calculations • Measures of spread-in-data, the range, interquartile-range, standard deviation and variance • Box plots • Interpreting the standard deviation measure using the rule-of-thumb and Chebyshev’s theorem ________________________________________ WEEK 2 Module 2: Descriptive Measures of Association, Probability, and Statistical Distributions This module presents the covariance and correlation measures and their respective Excel functions. You get to understand the notion of causation versus correlation. The module then introduces the notion of probability and random variables and starts introducing statistical distributions. Topics covered include: • Measures of association, the covariance and correlation measures; causation versus correlation • Probability and random variables; discrete versus continuous data • Introduction to statistical distributions ________________________________________ WEEK 3 Module 3: The Normal Distribution This module introduces the Normal distribution and the Excel function to calculate probabilities and various outcomes from the distribution. Topics covered include: • Probability density function and area under the curve as a measure of probability • The Normal distribution (bell curve), NORM.DIST, NORM.INV functions in Excel ________________________________________ WEEK 4 Module 4: Working with Distributions, Normal, Binomial, Poisson In this module, you'll see various applications of the Normal distribution. You will also get introduced to the Binomial and Poisson distributions. The Central Limit Theorem is introduced and explained in the context of understanding sample data versus population data and the link between the two. Topics covered include: • Various applications of the Normal distribution • The Binomial and Poisson distributions • Sample versus population data; the Central Limit Theorem...

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!

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!)

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.

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.

The course content was concise enough to breeze through it in under a dozen hours (for an engineer). The assignments and practice quizzes were very helpful. I was a bit disappointed that the content was very basic, but then again, this was not advertised as an advanced course.

I enjoyed this course. It was a good introduction to each concept with enough practice to help learn. Would need to be supplemented with more real world practice before i would feel comfortable using at work. Specifically, understanding random sampling.

The mathematical formulas can be a little confusing if you're not familiar with statistical math, but this is not the fault of the lecturer obviously.

Overall, a nicely explained and set out course. Really helpful and understandable for beginners.

It was great. Test was a little bit difficult for me, however after revising and studying again the lessons I was finally able to pas it, most important thing was not to pass the test but to understand the material better.

I liked how straightforward it was. Straight into the materials and their explanations, with examples, well explained, and all in very well paced videos. The mini-quizzes at the end of each lesson were also a major help.

Over a short span of a month, it feels as though I've progressed from extremely less to significantly good knowledge on Data descriptors and statistical distributions on a business perspective thanks to the course.
