Statistics practice problems from your own lectures and textbook
StudyPDF makes statistics practice problems from your own slides and textbook chapters, so the questions use your course's notation and cover what your exam covers.
- Hypothesis tests, distributions and software output
- Formulas written as math
- Tables and charts from your slides inside the question

Statistics practice problems that match your course
To get statistics practice problems that match your course, upload your lecture slides and textbook chapters to StudyPDF and make a quiz on one topic. The questions cover hypothesis tests, distributions and reading software output, with formulas written as math and the tables and charts from your slides shown inside the question. Short answers are self-graded against a model answer, and a timed practice exam comes before the final. It does not solve arbitrary homework step by step. This page shows what it does, with an example, and where it stops.
Hypothesis tests, from the setup to the conclusion
Say your lecture on hypothesis testing is uploaded. You press New material, choose Quiz, scope it to that lecture and ask for 15 questions with short answer included. A set like that can ask which test fits a sample mean, a standard deviation and a sample size, which statements about a p-value of 0.03 are true, and how to state the conclusion in the context of the study. Each question comes with an explanation and the slide it was built from, so a wrong answer sends you back to the right page.
Distributions and reading output
Exams love a table from R or SPSS and the question "is the slope significant at the 5 percent level?". If your slides show a histogram, a normal curve or a regression table, StudyPDF crops it from the page and can put it inside a question that starts "Using the table below". Questions on the normal, binomial and t distributions and on confidence intervals follow what your material teaches. Only figures that are in your upload appear. Nothing is drawn for you.
A timed practice exam before the final
A week before the exam, make a practice exam from the whole course. It has sections by topic, an optional timer and no feedback until you submit, like the real thing. You get a graded report with the result per section, and you mark the short answers yourself against the model answer. The concepts you missed go first into your next quiz, so the last days are spent on your gaps.
Fixed problem sets or questions from your course
Problem sets, university PDFs and videos are good for seeing worked examples, but they are fixed, and they may use other notation or cover other topics than your course. Once you have solved them, there is nothing left. StudyPDF makes new questions from your own slides and chapters and can make another set whenever you want. What it does not do: it does not solve any homework you paste in step by step, it is not statistics software, and it gives no official past papers. Check calculations against the explanation and the source page.
Three ways to practice better
Try the question before you look at the explanation. Writing down a test choice or a conclusion first shows you what you do not know yet, where reading a worked solution makes everything look obvious.
Use short answer for interpretation. Choosing the right test is half of statistics. The other half is saying what a result means in words, and that only gets better if you write it and compare it with the model answer.
After each quiz, look at the concepts you missed and make a new set on just those. Your results update your mastery per concept, so the next quiz can start from your weakest ones.
Make your first statistics quiz
Upload the slides and the textbook chapter for your next statistics exam, make a quiz on one topic and read the explanations on what you miss. When the exam gets close, finish with a timed practice exam. A free account is enough to start.
How to make statistics practice problems with StudyPDF
Four steps, from your lecture slides to a timed exam.
- 1
Upload your statistics material
Add lecture slides, textbook chapters, your formula sheet or photos of your notes to one course. Tables and charts are cropped out of the pages so they can come back inside questions.
- 2
Pick a topic and a question mix
Scope it to one lecture or topic, set the difficulty and the number of questions, and include short answer next to multiple choice if you want to explain a result in words.
- 3
Work through the questions
Formulas show as math. Where your slides have a chart or an output table, the question says "Using the chart below" and shows it.
- 4
Finish with a timed practice exam
Before the final, make a practice exam from the whole course: sections by topic, an optional timer and no feedback until you submit. You get a graded report per section, and your weak concepts come back first.

Questions and answers
Where can I find statistics practice problems?
Textbooks, university problem sets, Khan Academy and OpenStax all have them, and they are fixed sets. StudyPDF makes new ones from your own lecture slides and textbook chapters, so they follow your course and your professor's notation. You can make another set whenever you finish one.
Can StudyPDF make statistics problems from my lecture slides?
Yes. Upload the slides and textbook chapters to a course, press New material, choose Quiz and scope it to a lecture or a topic. You get questions on what those pages cover, with an explanation and the source page on each one.
Does it handle formulas, tables and charts?
Formulas are written as math. If your slides contain a chart or a table, such as a histogram or a regression output table, StudyPDF crops it from the page and can use it in a question that says "Using the chart below". It only uses figures that exist in your upload and does not draw new ones.
5 more questions
Does it solve my statistics homework step by step?
No. StudyPDF makes practice questions from your material and explains the answers it wrote. It does not take any homework problem you paste in and solve it step by step, and it is not a calculator or statistics software. For a calculation, check the result against the explanation and the source page.
How are short answers graded?
You grade them yourself. Write your answer, then compare it with the model answer and mark it right, partly right or wrong. That works well for questions like "state the conclusion in the context of the study", where the wording matters.
Can I take a timed statistics practice test?
Yes. Make a practice exam from your course with sections, an optional timer and no feedback until you submit. You get a graded report with results per section, and short answers are marked by you against the model answer.
Can I also make statistics flashcards or a study guide?
Yes, from the same course. New material also makes flashcards for formulas and definitions, a study guide, a cheat sheet and a summary. You can export any of them to PDF or Word, and flashcards to Anki.
Is it free?
Yes, to start. You need a free account, no card. Free gives you about 4 materials a week and 2 courses. Pro gives you about 35 materials a week and 10 courses. Every plan has a weekly cap.
