# edX: Introduction to Statistics: Descriptive Statistics

with  Ani Adhikari and Philip B. Stark
Class Central Course Rank
#3 in Subjects > Mathematics > Statistics & Probability

We are surrounded by information, much of it numerical, and it is important to know how to make sense of it. Stat2x is an introduction to the fundamental concepts and methods of statistics, the science of drawing conclusions from data.

The course is the online equivalent of Statistics 2, a 15-week introductory course taken in Berkeley by about 1,000 students each year. Stat2x is divided into three 5-week components. Stat2.1x is the first of the three.

The focus of Stat2.1x is on descriptive statistics. The goal of descriptive statistics is to summarize and present numerical information in a manner that is illuminating and useful. The course will cover graphical as well as numerical summaries of data, starting with a single variable and progressing to the relation between two variables. Methods will be illustrated with data from a variety of areas in the sciences and humanities.

There will be no mindless memorization of formulas and methods. Throughout Stat2.1x, the emphasis will be on understanding the reasoning behind the calculations, the assumptions under which they are valid, and the correct interpretation of results.

The professor's video presentations are excellent. She mixes a casual humor with an astonishing ability to communicate complex ideas and concepts clearly and articulately.

The online textbook, with its statistics calculators, is an excellent resource and great benefit of the course.

Excellent and very well organised course for an intro to stats. There is no software package needed to learn for the completion of the assignments and tests. Everything is provided and explained thoroughly.

Highly recommended.
