We live in a time of unprecedented access to information...data. Whether researching the best school, job, or relationship, the Internet has thrown open the doors to vast pools of data. Statistics are simply objective and systematic methods for describing and interpreting information so that you may make the most informed decisions about life.

Why Take This Course?
• The applications of statistics to everyday life
• Methods for acquiring data through observation and experimentation
• To organize and describe quantitative and categorical forms of data
• Anticipating patterns using basic probability and sampling
• Statistical inference through estimation and hypothesis testing
• Correlation and simple regression
• Ways of describing the strength of relationships between variables

by completed this course, spending 4 hours a week on it and found the course difficulty to be medium.
This class is perfect for the Statics beginner. It gives a thorough and easy to understand explanation about the key concepts in Statistics with examples and reinforcing exercises.

I was struggling at separating the mean (μ) for the sample mean (x-bar) and didn't have the slightest idea of what "standard deviation" was until I took this class. I'm very grateful for it and although it doesn't cover fully the topics of an intro to Stats class, it explains core concepts perfectly!

This course starts out simple and steadily accelerates in difficulty. I realized towards the end that the beginning of the course helped me build a strong foundation in understanding and analyzing distributions, which are key to all the statistical tests you learn later (e.g., z-tests, t-tests, chi-squared tests).
