Solve a whole statistics problem from a screenshot
Calculators need clean numbers. Homework rarely gives you that: it gives you a word problem, a frequency table, a chart and an answer box that wants three decimals. An AI statistics solver reads all of it at once.
- Open the problem in MyStatLab, ALEKS, WebAssign, McGraw Hill Connect, Canvas or any other page in Chrome.
- Press Ctrl+2 (Cmd+2 on Mac) and drag over the question, including the table or graph.
- Read the steps in the side panel: which test or formula applies, every intermediate value and the answer rounded the way the question asks.
Free plan included. Premium is from $4.99/month for 700 solutions.
Best statistics solvers in 2026
We compared the tools students actually use for statistics homework on four things: how you enter a problem, whether you see the steps, whether it works on the page where your homework is, and what is free.
| Tool | Best for | How you enter a problem | Steps | Free option |
|---|---|---|---|---|
| XMath AIOur pick | Word problems with tables and charts on homework sites | Screenshot in Chrome | Yes | Free plan |
| Wolfram|Alpha | Exact computations and distributions | Typed query | Pro | Answers are free |
| StatCrunch | Analysing whole data sets | Spreadsheet and menus | Output, not explanations | Usually through your course |
| Symbolab | Formula-based exercises | Typed or photo | Partly free | Limited |
| ChatGPT | Explaining concepts | Chat, image upload | Yes | Limited |
1. XMath AI — best for statistics homework in the browser
A Chrome extension: you select the problem on screen and it reads the text, the data table and the answer format together, so a z-test, a two-way table or a regression output does not have to be retyped. It explains which method applies and shows each step. Works on MyStatLab, ALEKS, WebAssign, McGraw Hill Connect, Canvas and other sites. Free plan; Premium from $4.99/month. XMath AI statistics solver.
2. Wolfram|Alpha — best computational engine
Very reliable when you can phrase the question yourself, for example “P(Z < 1.33)” or “95% confidence interval mean 52.3 sd 8.1 n 25”. Step-by-step solutions need Wolfram|Alpha Pro, and long word problems must be translated into a query first.
3. StatCrunch — best for data sets
Pearson's statistics software, often bundled with MyStatLab courses. Ideal for descriptive statistics, hypothesis tests and charts on a full data set. It produces output tables rather than explaining the method.
4. Symbolab — good for formula exercises
Has dedicated statistics calculators (mean, standard deviation, z-score and more) with steps. The full step-by-step view is part of the paid plan, and multi-part word problems are harder to enter.
5. ChatGPT — good for understanding concepts
Useful for “why do we use t here?” questions and for checking your reasoning. As a general chatbot it can slip on table lookups and arithmetic, so verify the final numbers.

How to solve the most common statistics problems
Mean and standard deviation
Add the values and divide by n to get the mean. For the sample standard deviation, square each deviation from the mean, add them, divide by n − 1 and take the square root.
s = √( Σ(x − x̄)² / (n − 1) )Z-scores and normal probability
A z-score tells how many standard deviations a value is from the mean. Convert, then read the area to the left from the standard normal table.
z = (x − μ) / σConfidence interval for a mean
Find the critical value (z* if σ is known, otherwise t* with n − 1 degrees of freedom), multiply by the standard error to get the margin of error, then add and subtract it from x̄.
x̄ ± t* · s / √nHypothesis test
State H₀ and H₁, compute the test statistic, find the p-value for the correct tail and compare it with α. Reject H₀ when p < α, and write the conclusion in the words of the problem.
t = (x̄ − μ₀) / (s / √n)Linear regression
The slope is the sum of cross-deviations over the sum of squared x-deviations; the line always passes through (x̄, ȳ). r² is the share of variation in y explained by x.
b₁ = Sxy / Sxx, b₀ = ȳ − b₁x̄Probability and the binomial distribution
Use the binomial model when there is a fixed number of independent trials with the same success probability. “At least” and “at most” questions are sums of individual probabilities.

What is the best statistics solver?
For homework that lives in a browser (MyStatLab, ALEKS, WebAssign, McGraw Hill Connect, Canvas quizzes) our pick is XMath AI: you take a screenshot of the problem, including its data table or chart, and get the steps without retyping anything. For typed computations Wolfram|Alpha is the strongest engine, and for working with whole data sets StatCrunch is the standard tool in many courses.
Is there a free statistics solver with steps?
Yes. The calculators on this page are free and show every step: mean, standard deviation, z-scores, normal probabilities, confidence intervals, regression and binomial probability. XMath AI also has a free plan for solving full word problems from a screenshot.
Can AI solve statistics problems from a picture?
Yes. Screenshot-based solvers such as XMath AI read the problem text, the data table and the answer format from the image, then work through the method step by step. Always check that the solver used the right test and the right tail before you submit.
Should I use the sample or the population standard deviation?
Use the sample standard deviation s (divide by n − 1) when your numbers are a sample from a larger group, which is the usual case in homework. Use the population standard deviation σ (divide by n) only when the data is the entire population.
When do I use t instead of z for a confidence interval?
Use z when the population standard deviation σ is known. Use t with n − 1 degrees of freedom when you only have the sample standard deviation s, which is the common case.
