More detail
Stats is where intuition and formulas have to align: iTutor explains each test (t-test, chi-square, ANOVA, regression) by walking through assumptions, the test statistic, and interpretation. Generates problem sets from textbooks (Moore/McCabe, Devore, Wackerly), practice with real datasets, and conceptual flashcards on distributions. Useful for AP Stats, undergrad stats, biostats, and applied data-science courses.
