Student Study Site

The open-access Student Study Site includes the following:

  • Easy to use data sets for lessons
  • "On Your Own"exercises aimed to help students test their data literacy

It is a very useful and easy-to-follow book. I intend to recommend it to my students as a complimentary source to gain an understanding of the context, concepts and main steps for doing data driven journalism.

A very useful book, and I am using it as a supplemental text. The book uses Excel as the analytic tool -- normally a very good choice -- be we are using SPSS in the class. I have recommended the students buy their own copies if they intend to conduct analyses on their own or for their employer in the future, where SPSS may not be available.

SAGE Research Methods is a research methods tool created to help researchers, faculty and students with their research projects. SAGE Research Methods links over 175,000 pages of SAGE’s renowned book, journal and reference content with truly advanced search and discovery tools. Researchers can explore methods concepts to help them design research projects, understand particular methods or identify a new method, conduct their research, and write up their findings. Since SAGE Research Methods focuses on methodology rather than disciplines, it can be used across the social sciences, health sciences, and more.

With SAGE Research Methods, researchers can explore their chosen method across the depth and breadth of content, expanding or refining their search as needed; read online, print, or email full-text content; utilize suggested related methods and links to related authors from SAGE Research Methods' robust library and unique features; and even share their own collections of content through Methods Lists. SAGE Research Methods contains content from over 720 books, dictionaries, encyclopedias, and handbooks, the entire “Little Green Book,” and "Little Blue Book” series, two Major Works collating a selection of journal articles, and specially commissioned videos.
