Descriptive Stats

AP Stats formulas

Descriptive: x̄=Σx/n, s=√(Σ(x-x̄)²/(n-1)), ŷ=a+bx

χ²: χ²=Σ(obs-exp)²/exp

CI: stat ± (critical)×(SE)

Binomial

P(X=x) for Binomial(n, p)

Geometric

Binomial: P(X=x)=C(n,x)pˣ(1-p)ⁿ⁻ˣ

Geometric: P(X=x)=(1-p)ˣ⁻¹p

Z-table

P(Z < z) and P(Z > z)

t-table

Critical value t* for confidence interval

χ²-table
