Statistics 2 at Berkeley is an introductory class taken by about 1,000 students each year. Stat2.3x is the last in a sequence of three courses that make up Stat2x, the online equivalent of Berkeley's Stat 2. The focus of Stat2.3x is on statistical inference: how to make valid conclusions based on data from random samples. At the heart of the main problem addressed by the course will be a population (which you can imagine for now as a set of people) connected with which there is a numerical quantity of interest (which you can imagine for now as the average number of MOOCs the people have taken). If you could talk to each member of the population, you could calculate that number exactly. But what if the population is so large that your resources will not stretch to interviewing every member? What if you can only reach a subset of the population?

Stat 2.3x will discuss good ways to select the subset (yes, at random); how to estimate the numerical quantity of interest, based on what you see in your sample; and ways to test hypotheses about numerical or probabilistic aspects of the problem.

The methods that will be covered are among the most commonly used of all statistical techniques. If you have ever read an article that claimed, "The margin of error in such surveys is about three percentage points," or, "Researchers at the University of California at Berkeley have discovered a highly significant link between ...," then you should expect that by the end of Stat 2.3x you will have a pretty good idea of what that means. Examples will range all the way from a little girl's school science project (seriously – she did a great job and her results were published in a major journal) to rulings by the U.S. Supreme Court.

The fundamental approach of the series was provided in the description of Stat2.1x and appears here again: There will be no mindless memorization of formulas and methods. Throughout the course, the emphasis will be on understanding the reasoning behind the calculations, the assumptions under which they are valid, and the correct interpretation of results.

Statistics 2 at Berkeley is an introductory class taken by about 1000 students each year. Stat2.2x is the second of three five-week courses that make up Stat2x, the online equivalent of Berkeley's Stat 2.

The focus of Stat2.2x is on probability theory: exactly what is a random sample, and how does randomness work? If you buy 10 lottery tickets instead of 1, does your chance of winning go up by a factor of 10? What is the law of averages? How can polls make accurate predictions based on data from small fractions of the population? What should you expect to happen "just by chance"? These are some of the questions we will address in the course.

We will start with exact calculations of chances when the experiments are small enough that exact calculations are feasible and interesting. Then we will step back from all the details and try to identify features of large random samples that will help us approximate probabilities that are hard to compute exactly. We will study sums and averages of large random samples, discuss the factors that affect their accuracy, and use the normal approximation for their probability distributions.

Be warned: by the end of Stat2.2x you will not want to gamble. Ever. (Unless you're really good at counting cards, in which case you could try blackjack, but perhaps after taking all these edX courses you'll find other ways of earning money.)

Biological systems are dynamic, complex, and made of many parts. In the past, scientists often tried to understand them by examining each constituent part. However, this approach was unsuccessful in many cases because the parts of any complex biological system can “interact” with each other and understanding such interaction is critical.

In this biology and life sciences course you will learn about systems biology, a holistic approach to understanding biological complexity, focusing on how all of the parts of a system work together. This course will teach you the basic concepts of systems biology, including engineering principles and tools developed for dynamic systems (e.g., robots) to better model and understand biological dynamics.

You will learn how simple math operations, addition and multiplication, can be used to model and simulate dynamic biological behaviors. Different types of “gene circuits” will be modeled and simulated using Octave Online, a web-based programming tool.

This course is geared towards secondary/ high school STEM (Science, Technology, Engineering and Math) educators and students. Basic programming skills will be taught in a step-wise manner so no prior programming experience or knowledge is necessary.

Three things are clear about today’s music industry: The consumption of music is expanding at the greatest rate in history and from the most portals ever imagined, the cost of producing music is decreasing, and the number of artists creating and seeking to expose their work and develop careers through the Internet has increased dramatically. As demand grows and Internet piracy wanes, ad-supported and subscription models will generate unprecedented revenues that will surpass even the best of past earnings. And, many astute “music industry-watchers” predict a steep rise in business activity and trade earnings by the end of the decade.

Whether you’re a music creator, consumer, or facilitator of this process, you’ll want to understand the history, underpinnings, and basics of the music business. This course has been developed to provide students with the latest instruction on the best way for creators, consumers, and facilitators to navigate the resurgence of one of the world’s most exciting industries: the music business. Course author John Kellogg—administrator, educator, entertainment lawyer, performer, and radio and television personality—offers students the opportunity to learn the fundamental principles of the developing new music business, for now and into the future.
