À propos du cours

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...

This course was great. Although the concepts introduced are complex, the instructor breaks them down and gives relatable, real-world style examples to easily explain the application.

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!)

the last portion was really difficult to understand, the material was too general for the questions covered in the quiz.

Wonderfully structured course!. There is something about this specialization, the manner in which it is created, that keeps you entrhalled all the time. Totally a big green light to someone looking to indulge oneself in the business statistics concepts. Thank you so much sir! Looking forward to other courses of the specialisation.

Contains all basic information on data descriptors, presented in a thorough and easy to understand way. More practice exercises (quizzes) would make it even better.

Clear and concise introduction to a number of statistical concepts. What this course lacks is application exercises in excel. It is taught well, but could benefit by expanding the course material to work with more problem sets in actual excel. For this one reason the cost of the course may not be worth it if you are unable to finish 2 to 3 courses in a month (imho).

what a good course and i love all exercises special the 4 final exams each week and i want more exercise for practice some of exercises not easy to understand need to practice more every week

next time want to see more exercises or more outsources exams
