What it solves

Hypothesis testing

One- and two-sample z and t tests, paired tests, proportions, chi-square and ANOVA — hypotheses stated, test statistic computed, p-value interpreted in context.

Probability & distributions

Binomial, Poisson, geometric, normal and t distributions, plus conditional probability, Bayes' theorem and expected value with the formula shown each time.

Descriptive statistics

Mean, median, mode, variance, standard deviation, quartiles, IQR, outliers and five-number summaries worked out from raw data or frequency tables.

Confidence intervals

Intervals for means and proportions, margin of error, critical values and sample-size calculations, with each substitution written out.

Correlation & regression

Scatterplot interpretation, correlation coefficient, least-squares regression lines, residuals, r² and predictions from the fitted model.

Worked examples

Hypothesis test

n = 40, x̄ = 12.4, s = 2.1, test μ = 12 at α = 0.05

One-sample t test → t ≈ 1.20, p ≈ 0.237 → fail to reject H₀

Probability

P(X = 3), X ~ Binomial(n = 10, p = 0.2)

C(10,3)·0.2³·0.8⁷ ≈ 0.2013

Confidence interval

95% CI for p̂ = 0.62, n = 250

0.62 ± 1.96·√(0.62·0.38/250) → (0.560, 0.680)

How it works

  1. 1

    Paste the data or photograph it

    Type the question and its numbers, or attach a picture of the table straight from your phone camera.

  2. 2

    Read the worked solution

    Each step names the formula or test used and shows the substitution in proper math notation.

  3. 3

    Ask follow-up questions

    Stay in the same conversation and ask why a test was chosen until the reasoning makes sense.

Statistics solver FAQ

Can the statistics solver run hypothesis tests?

Yes. Give it the sample data or summary statistics and it states the null and alternative hypotheses, picks the right test (z, t, chi-square, ANOVA), computes the test statistic and p-value, and writes the conclusion in context.

Which statistics topics are covered?

Descriptive statistics, probability rules, discrete and continuous distributions (binomial, Poisson, normal, t), sampling distributions, confidence intervals, hypothesis testing, chi-square tests, ANOVA, correlation and linear regression.

Does it show the formula and the working?

Every step names the formula used and shows the substitution, so you can see where each number comes from instead of only the final answer.

Can I upload a photo of a statistics problem or data table?

Yes. Attach a photo or screenshot of the worksheet, data table or output. The solver reads the values from the image and works from them directly.

Is the statistics solver free?

You get 2 free answers when you create an account. Pro is $9.99 per month for unlimited step-by-step solutions.
