Statistics for Psychologists: An Online Textbook

The materials in this online textbook are intended to facilitate the connection between standard introductory statistics concepts and their implementation in statistical software. The textbook currently includes: a summary of basic statistical methods; instructions on obtaining basic statistical output using SPSS, JAMOVI, and JASP; annotated output showing how to calculate and interpret the output; and summaries of how the results should be reported in APA style.

Estimation Approach to Statistics with Excel (EASE)

EASE is a set of fast and easy spreadsheets that calculate confidence intervals for means and standardized effect sizes, the later of which are not available in more elaborate commercially available statistical software. Separate spreadsheets are available for different designs (between-subjects vs. within-subjects) and data input type (raw data vs. descriptive statistics). All sheets are updated regularly.

Arelational and Relational Interval Staistics with Excel (ARISE)

ARISE is a fork of my EASE project. ARISE spreadsheets calculate both relational and arelational confidence intervals for means. Separate spreadsheets are available for different designs (between-subjects vs. within-subjects). Both assume the use of raw data.
