## Description

Statistics solver with step by step working. Photograph a statistics problem to get the right test and the full solution.<br><br>WHICH STATISTICAL TEST?<br>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.<br><br>ASSUMPTIONS CHECKED<br>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.<br><br>WHAT THIS STATISTICS SOLVER COVERS<br>• Mean, median, mode, variance, standard deviation<br>• Probability and conditional probability<br>• Normal, binomial and Poisson distributions<br>• Confidence intervals and hypothesis testing<br>• One sample, paired and independent t-tests<br>• Chi-square, ANOVA and regression<br><br>WHAT A P-VALUE MEANS<br>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.
