Diffusion model analysis (slides)
Reliability (slides)
(For this talk, make sure to understand correlation and one-sample t-test)
Software solutions
Which type of software to choose (slides)
(For this talk, make sure to understand the basic descriptive statistics, hypothesis tests, interval estimation, and standardized effect size.)
Hypothesis tests
The reasoning behind the tests and the main consequences (slides)
Bayesian analysis (slides - coming soon)
Descriptives
Describing a single variable (slides)
Describing the relation of two variables (slides)
Fitting functions
Optional workshop on 19 October (date will be modified)
Comparing variables and groups (slides)
Statistical analysis with computer programming (optional topic)
Statistics in Python
The next two requirements should be fulfilled. (Second, optional topics should be approved, the deadline is 14 October extended deadline is 11 November)
Exam with practical tasks. At the end of the term time.
Choose one of the topics below. The deadline is the date of the last lecture. Update: the deadline for the written report/material is still 9 December, but the date of the presentation is 2 December.
Create a new or extend an existing Wikipedia article in English or in Hungarian on statistics or data analysis topics (e.g., statisztika téma) (for Hungarian speakers, this might help: leírás). You can translate the article from another language, if the source language includes high-quality material. Minimum length is 6000 characters (with spaces) for new material or for extensions, and 8000 characters for translations.
A few Hungarian articles from the last years: A statisztika helytelen használata, Feltáró faktorelemzés, Ellenőrző faktorelemzés, Mintavételi hiba, Lineáris diszkriminancia-analízis
Review related tasks: (0) Add your topic and review to this list. Ask for permission, which I'll approve automatically. (1) After completing your article, you should send it to another student (reviewer) so they can add comments and suggestions. The deadline is 10 days before the final deadline. (2) Your peer will review the text and will send it back to you. The deadline is 5 days before the final deadline. (3) Finalize your article, then send me your final version, your peer's comments, and the version you sent to your peer.
(Only in Hungarian) Új szócikk készítése vagy kiegészítése a Statisztika a pszichológiai kutatásban weboldalra. Legkevesebb 5000 karakter szóközzel.
CogStat (choose one from the list below)
Localize it to a new language, or improve and/or extend previous localizations.
Propose new procedures with appropriate justifications.
A few examples (mostly the topics with the "question" label)
An empirical test of the efficiency of various statistical software types
Analyze your previous results insome non-traditional way.
Contact me about the chosen topic and methods.
Implementing extra statistical or data analysis functions for LibreOffice. (This could be implemented either as a Basic script or a spreadsheet template.)
If you have any further ideas that are related to the topics of the course and which could be useful for you and/or for others, contact me about the idea.
Micro oral report about the chosen task. In the last lecture.
In a maximum of 5 minutes, summarize the most unexpected details of the work you've done. Slides are optional.
If you did not have any statistical courses before, you may have this course as an intro course with some advanced topics.
There'll be an exam in the last class. Mostly, you'll get data files, and specific questions (e.g., is there a gender difference in the GSLK test (the GSLK is totally made up)), and the reply should be given in APA style. There will be a few questions regarding the original topics of the class too.
As a preparation, you should read about specific topics at home, and we will discuss the chapters in the class.
The www.learningstatisticswithcogstat.com book is recommended, but any other books with similar topics can be used (see the Recommended materials below).
Chapters to be discussed:
October 28: Chapters 1-6
November 11: Chapters 7-10
November 25: Chapters 11-14
For the exam: data file, submission form.
Software packages we may use:
