START WHERE YOU ARE
One curriculum. Your own way through.
01 / BUILD A FOUNDATION
“I’m new to this.”
Start with variables, graphs, probability, and the language of research.
Start from the basics →02 / CONNECT THE DOTS“Help me with my course.”
Find the method you’re studying, then work from an example to independent practice.
Support my course →03 / PUT IT TOGETHER“I’m preparing for an exam.”
Check a topic, practise what needs work, and return later to test retention.
Prepare for an exam →THE CURRICULUM
Build understanding that travels.
General linear models
ANOVA, repeated measures, factorial designs, ANCOVA, regression, MANOVA, and classification.
Measurement & advanced methods
Reliability, validity, factor analysis, IRT, structural equation models, and multilevel models.
BUILT FOR LEARNING
Understand the method.
Then put it to work.
MethodSpring is the learning companion to ProjectRAgent, Gradual Genius’s statistical workbench. Here, you can explore a method safely, interpret provided outputs, and practise reporting before working on your own research.
Classroom reviewers can explore the full teaching sequence with a clearly labeled synthetic class.

GOOD QUESTIONS
Before you begin.
Do I need SPSS or an OpenAI account?
No. Required activities use provided data and instructional output tables in your browser. Optional software exercises include downloads. AI, when enabled, is provided through Gradual Genius.
What does a free account add?
Save progress across devices, export your history, and access limited AI assistance after email verification and the AI quality gate. Guest progress stays in this browser.
Is this a graded course or certification?
No. This is a study tool. Progress estimates, self-assessments, and AI suggestions do not constitute accredited grades. Imported curriculum is labeled pending subject review.
Can I use it in a class?
Yes: use lessons, practice, labs, and student exports. The instructor showcase demonstrates future class management using synthetic data; it does not send assignments or collect a real class roster.
