“Which test am I supposed to use?”
Work from the study design, not the chapter heading. Choose the Test problems ask you to identify the right method without being told its name.

When understanding isn't enough
Familiar in your notes.
Harder on a blank page.
If these moments sound familiar, this is what you will practice.
“I have the output. What does it mean?”
Practice reading SPSS, JASP, and G*Power output, identifying what matters, and explaining what the numbers support.
“I knew this a few weeks ago.”
Earlier topics return throughout the schedule. By Week 8, questions are mixed and unlabeled, so you practice recognizing the method yourself.
What you'll practice
Five skills.
More than getting a number.
-
A
Choose the test
Match the research design to the appropriate statistical method.
-
B
Calculate & interpret
Work through the calculation, then explain what your answer means.
-
C
Read the output
Turn a software table into a supported conclusion.
-
D
Write it in APA
Practice reporting results in a clear, correctly structured sentence.
-
E
Find the error
Spot flawed interpretations, unsuitable tests, and claims that go too far.
Your eight-week roadmap
Know what to work on next.
Each week includes six days of problems, a closed-book self-check, fully worked solutions, and source references. Check the topics against your course syllabus.
WEEK 01 Descriptives, distributions & z-scores
Central tendency, variability, normal distributions, and interpreting scores in psychology.
WEEK 02 Sampling & statistical inference
Sampling distributions, standard error, p-values, Type I and Type II errors, and statistical power.
WEEK 03 t-tests & choosing between them
One-sample and independent-samples tests, assumptions, Welch's correction, and test selection.
WEEK 04 Paired designs, effect sizes & intervals
Paired-samples tests, Cohen's d, and interpreting the size and precision of an effect.
WEEK 05 ANOVA & multiple comparisons
One-way ANOVA, follow-up comparisons, and reporting effect size.
WEEK 06 Correlation & simple regression
Interpreting associations, regression output, predictions, and their limitations.
WEEK 07 Categorical & rank-based tests
Chi-square and rank-based approaches, with practice choosing and interpreting tests.
WEEK 08 Mixed practice & integration
Problems from across the program, mixed and unlabeled, plus a final closed-book self-check.
How to use it
A routine you can follow.
Plan for around 25–40 minutes a day, six days a week. Reserve day seven for your closed-book self-check.
Try three problems.
Work through the day's questions before opening the solutions. Write your answer and your reasoning.
Check. Close. Try again.
Compare your work with the fully worked solutions. If you get stuck, review the explanation, close it, and rebuild the answer yourself.
Find out what stayed.
Use the weekly self-check and its scoring guidance to decide whether to move on, revisit specific days, or repeat the week.
Included with your system
Three tools to support your practice.
104-Card Statistics Recall Deck
Use short prompts to revisit key concepts and practice recalling them without looking at your notes.
APA Results Sentence Bank
Keep examples of results sentences beside you while practicing how to report your own answers.
Evidence & Sources Guide
Explore the references behind the system and its approach to practice.
Also included: the Test Decision Tree. A companion reference to help you work through test selection.

Before you start
Your questions, answered.
What exactly do I receive?
The 255-page Psychology Statistics Practice System with 144 problems and worked solutions, the Test Decision Tree, and three study bonuses: the Recall Deck, APA Results Sentence Bank, and Evidence & Sources Guide. This is a digital product.
Do I need SPSS or JASP installed?
No. The output needed for the exercises is printed inside the problems. Have a calculator, paper, and the relevant statistical tables from your course or textbook available.
How much time should I set aside?
Around 25–40 minutes a day for three problems, six days a week, plus a closed-book self-check on day seven. The final Week 8 self-check is designed for 90 minutes.
Can I use it if my exam is soon?
You can focus on topics you need to review, but the full schedule is designed for eight weeks. Compressing everything into a few days changes the spacing built into the program.
Will it match my course?
Compare the eight-week roadmap above with your syllabus. The system covers core introductory statistics topics used in psychology; your course may include additional material.
What if I struggle with a self-check?
Follow the scoring guidance to review specific days or repeat the week. The check is there to identify what needs more practice before you move forward.
How do I access the materials?
Your download link is provided after checkout and by email. Read the PDF on a compatible device or print the pages you want to work on.
Give your next study session
a clear starting point.
Start with three problems. Check your reasoning. Build a routine that brings earlier material back into practice.
