About this app

Statistics solver with step by step working. Photograph a statistics problem to get the right test and the full solution.

WHICH STATISTICAL TEST?
This statistics solver identifies the appropriate test and says why. Continuous data across two independent groups points to an independent t-test; the same subjects measured twice points to a paired t-test; three or more groups points to ANOVA; categorical counts point to chi-square.

ASSUMPTIONS CHECKED
Most tests assume normality, equal variances or minimum expected counts. A test applied where its assumptions fail produces a confident number that means nothing, so the app flags it and suggests the non-parametric alternative.

WHAT THIS STATISTICS SOLVER COVERS
• Mean, median, mode, variance, standard deviation
• Probability and conditional probability
• Normal, binomial and Poisson distributions
• Confidence intervals and hypothesis testing
• One sample, paired and independent t-tests
• Chi-square, ANOVA and regression

WHAT A P-VALUE MEANS
The probability of data at least as extreme as yours if the null hypothesis were true — not the probability the null is true. The app states the interpretation properly, because that is where the marks are.
