AP Stats: Calculator Commands Review

Flashcards for reviewing calculator commands on the TI-84 for AP Statistics, covering statistical calculations, distributions, and tests.

normalcdf(-1E99, UB)

Calculates the area under the z-distribution to the left of an upper bound (UB).

normalcdf(LB, -1E99)

Calculates the area under the z-distribution to the right of a lower bound (LB).

normalcdf(LB, UB)

Calculates the area under the z-distribution between a lower bound (LB) and an upper bound (UB).

tcdf(LB, UB, df)

Calculates the area under the t-distribution between a lower bound (LB) and upper bound (UB) with specified degrees of freedom (df).

Xsquared-cdf(LB, UB, df)

Calculates the area in the tail of the Chi-Square distribution between a lower bound (LB) and an upper bound (UB) with specified degrees of freedom (df).

invNorm(area)

Finds the z-score corresponding to a given area in the tail (percentile).

invT(area of tail, df)
