What Is an Ap Stats Calculator?
An Ap Stats Calculator is a free browser tool that runs every statistical function on the AP® Statistics exam. It covers normal distribution, binomial probability, z-score, p-value, t-test, chi-square test, confidence interval, and linear regression, with the same outputs as a TI-84 Plus or TI-Nspire — no login, no download, and no data leaves your browser. Students use it for homework checks, AP exam practice, and score estimation, following the College Board weights: multiple choice 50% and free response 50%. It matches TI-84 Plus outputs to at least 6 decimal places, and unlike Desmos it uses TI-84 function names and menus, so the skills transfer directly to the exam.
Score formula
Composite = (MCQ ÷ 40) × 50 + (FRQ Q1–Q5 ÷ 20) × 37.5 + (Q6 ÷ 4) × 12.5
MCQ is 50% of the score, FRQ Q1–Q5 is 37.5%, and the investigative task Q6 is 12.5%.
