Comparing Two Group Means : The Independent Samples t Test
Found in: Interpreting and Using Statistics in Psychological Research
By:Content Type: books
Publisher: SAGE Publications, Inc (2017)
This practical, conceptual introduction to statistical analysis by award-winning teacher Andrew N. Christopher uses published research with inherently interesting social sciences content to help students make clear connections between statistics and real life. Using a friendly, easy-to-understand presentation, Christopher walks students through the hand calculations of key statistical tools and provides step-by-step instructions on how to run the appropriate analyses for each type of statistic in SPSS and how to interpret the output. With the premise that a conceptual grasp of statistical techniques is critical for students to truly understand why they are doing what they are doing, the author avoids overly formulaic jargon and instead focuses on when and how to use statistical techniques appropriately.

Paired Samples t Test (Dependent Samples t Test)
Found in: Encyclopedia of Measurement and Statistics
Edited by:Content Type: encyclopedias
Publisher: Sage Publications, Inc. (2007)
SAGE Reference is proud to announce the Encyclopedia of Measurements and Statistics. In fields as varying as education, politics and health care, assessment and the use of measurement and statistics have become an integral part of almost every activity undertaken. These activities require the organization of ideas, the generation of hypotheses, the collection of data and the interpretation, illustration and analysis of data. No matter where we look, this critical analysis is more important than ever in an age where information - and lots of it - is readily available. The average consumer must know what a `median' is or what the connotations of the term `significant' are when intelligently reading The Times, Science News or a tabloid. Likewise, students, practitioners and researchers must grapple with sophisticated terms and techniques when conducting research, writing proposals and analyzing data. The terms themselves have proven to be anxiety-provoking. The Encyclopedia of Measurement and Statistics, in two-volumes, presents state-of-the-art information and ready-to-use facts from the fields of measurement and statistics in a non-intimidating and accessible style. The Encyclopedia is specifically written to appeal to undergraduate students as well as practitioners, researchers and consumers of information. Whilst there are reference works covering statistics and assessment in depth, none provide as comprehensive a resource in as focused and approachable a manner as this encyclopedia. Key themes include: - biographies; - charts, graphs and visual displays; - computer topics and tools; - concepts and issues in measurement; - concepts and issues in statistics; - data and data reduction techniques; - descriptive statistics; - evaluation; - experimental methods; - inferential statistics; - organizations and publications; - predictions and estimations; - probability; - qualitative methods; - samples, sampling and distribution; - statistical techniques; - statistical tests; - tests by name. Key features include: - coverage of every major facet of these two different, but highly integrated disciplines with reference to mean, mode and median; reliability, validity, significance and correlation without overwhelming the informed reader; - cross-disciplinary coverage, with contributions from and applications to the fields of: psychology; education; sociology; human development; political science; business and management; and public health; - cross-referenced terms, a list of further readings and Website URLs after each entry, as well as an extensive set of appendices and an annotated list of organizations relevant to measurement and statistics. Appendices: - Appendix A is a guide to basic statistics for those readers who require an instructional step-by-step presentation of basic concepts in statistics and measurement; - Appendix B is a table of critical values used in hypothesis testing and an important part of any reference in this area; - Appendix C represents a collection of some most important and useful measurement and statistics Websites.

t-Test, Independent Samples
Found in: The SAGE Encyclopedia of Communication Research Methods
Edited by:Content Type: encyclopedias
Publisher: SAGE Publications, Inc (2017)
Communication research is evolving and changing in a world of online journals, open-access, and new ways of obtaining data and conducting experiments via the Internet. Although there are generic encyclopedias describing basic social science research methodologies in general, until now there has been no comprehensive A-to-Z reference work exploring methods specific to communication and media studies. Our entries, authored by key figures in the field, focus on special considerations when applied specifically to communication research, accompanied by engaging examples from the literature of communication, journalism, and media studies. Entries cover every step of the research process, from the creative development of research topics and questions to literature reviews, selection of best methods (whether quantitative, qualitative, or mixed) for analyzing research results and publishing research findings, whether in traditional media or via new media outlets. In addition to expected entries covering the basics of theories and methods traditionally used in communication research, other entries discuss important trends influencing the future of that research, including contemporary practical issues students will face in communication professions, the influences of globalization on research, use of new recording technologies in fieldwork, and the challenges and opportunities related to studying online multi-media environments. Email, texting, cellphone video, and blogging are shown not only as topics of research but also as means of collecting and analyzing data. Still other entries delve into considerations of accountability, copyright, confidentiality, data ownership and security, privacy, and other aspects of conducting an ethical research program. Features: • 652 signed entries are contained in an authoritative work spanning four volumes available in choice of electronic or print formats. • Although organized A-to-Z, front matter includes a Reader’s Guide grouping entries thematically to help students interested in a specific aspect of communication research to more easily locate directly related entries. • Back matter includes a Chronology of the development of the field of communication research; a Resource Guide to classic books, journals, and associations; a Glossary introducing the terminology of the field; and a detailed Index. • Entries conclude with References/Further Readings and Cross-References to related entries to guide students further in their research journeys. • The Index, Reader’s Guide themes, and Cross-References combine to provide robust search-and-browse in the e-version.
