Statistics Test
Practice statistics from descriptive summaries to inference and regression
- ✓ Descriptive Statistics
- ✓ Probability
- ✓ Distributions
- ✓ Inference & Regression
Test Overview
Topics Covered
Master these essential concepts that are fundamental to Science
Descriptive Statistics
Mean, median, spread, standard deviation, quartiles and the shape of data
Probability
Sample spaces, the addition and multiplication rules, conditional probability and Bayes
Distributions
Random variables, the binomial and normal distributions, z-scores and the empirical rule
Inference & Regression
Sampling and the CLT, confidence intervals, p-values, correlation and least-squares lines
How It Works
Pick Difficulty
Choose a difficulty and how many questions you want
Solve Problems
Work through computational and conceptual multiple-choice questions
Review Explanations
See a worked explanation for every question after you answer
Track Progress
Watch your accuracy improve across statistics topics
Tips for Success
Read whether a question asks for a sample or a population standard deviation
For probability, decide if events are independent or mutually exclusive first
Remember a p-value is not the probability that the null hypothesis is true
Correlation measures linear association only — and never proves causation
Frequently Asked Questions
From introductory descriptive statistics through first-year university topics such as the Central Limit Theorem, confidence intervals and regression.
A basic calculator helps on the computational questions; many conceptual questions test understanding rather than arithmetic.
