New Study Guide for MA121: Introduction to Statistics from Saylor Academy

We use statistics everyday, in nearly every sphere of study – politicians use them to gage how voters will vote, investors use them to predict stock market performance, businesses use them to help design and market their products, store owners use them to decide which products to buy to stock their stores.

You do not need to be a researcher to benefit from this course. Understanding statistics will help you understand the business and political world, and may help you leverage your career.

Professor David Britz, math instructor at Spokane Community College, database designer, and programmer, has created this new study guide to help you understand statistics, pass the Saylor Academy final exam, and help you better comprehend the world around you.
