كيف يعمل

  1. 01

    Enter or photograph the problem

    Type the statistics problem or paste in a small dataset. Photos of textbook problems including tables work too.

  2. 02

    ScanSolve identifies the test

    z-test, t-test, chi-square, ANOVA, regression — the AI picks the right approach based on the data and question wording.

  3. 03

    Walk through the solution

    Each step shows the formula, the substitution, and the interpretation. Final answer comes with what the result means in plain English.

ما الذي يميّز ScanSolve

  • Interprets the result, not just computes

    ScanSolve writes “we reject the null hypothesis at α=0.05 because p=0.03” — it tells you what the p-value MEANS, not just spits out a number.

  • All major tests covered

    Hypothesis testing (z, t, chi-square, F), ANOVA, simple and multiple regression, correlation, confidence intervals, probability.

  • Distribution help built-in

    Normal, binomial, Poisson, geometric, hypergeometric — ScanSolve picks the right one and explains why.

  • AP-Stat curriculum aligned

    Solutions match the AP Statistics scoring rubric for FRQs — assumptions stated, formulas labeled, conclusions tied to context.

  • Photo input for table problems

    Snap a photo of a textbook problem with a frequency table, ANOVA output, or regression printout. ScanSolve reads it and continues.

ما الذي يغطّيه

  • AP Statistics

    FRQ-style step-by-step solutions matching the College Board rubric.

  • College Intro Stats

    Service-course statistics for psych, bio, business, social sciences.

  • Business Stats

    Regression, forecasting, quality-control distributions.

  • Biostatistics

    Two-sample tests, ANOVA, survival-analysis intro topics.

  • Probability Theory

    Counting, conditional probability, Bayes’ theorem, expected value.

الأسئلة الشائعة

Does ScanSolve compute p-values?

Yes. ScanSolve walks through the test statistic calculation step-by-step, then computes the p-value and explains what it means in the original problem context.

Can it do regression homework?

Yes. Simple and multiple linear regression with full interpretation: coefficients, R², residual analysis, and prediction intervals.

Is the statistics solver free?

Yes. 5 free step-by-step solutions per day, no card required.

How does it compare to a graphing calculator’s stats functions?

A graphing calculator gives you the test statistic and p-value. ScanSolve walks through the entire problem — assumptions, hypotheses, calculation, decision, and interpretation — which is what stats homework actually requires.
