A TI-84 Plus CE calculator is an indispensable tool on the AP® Statistics exam, saving critical minutes on complex computations. Here is the step-by-step keystroke guide for every distribution, test, and interval you will encounter.
| Command | Keystrokes | Input Syntax | When to Use |
|---|---|---|---|
normalcdf |
[2nd] [VARS] -> 2 | (lower, upper, $\mu$, $\sigma$) |
Find area under normal curve between two values. Use $-1\text{E}99$ or $1\text{E}99$ for $\pm\infty$. |
invNorm |
[2nd] [VARS] -> 3 | (area, $\mu$, $\sigma$, [LEFT/CENTER/RIGHT]) |
Find $z^*$ or $x$ value for a given percentile area. |
binompdf |
[2nd] [VARS] -> A | (trials, $p$, $x$) |
Find probability of exactly $x$ successes: $P(X = k)$. |
binomcdf |
[2nd] [VARS] -> B | (trials, $p$, $x$) |
Find cumulative probability of at most $x$ successes: $P(X \le k)$. |
tcdf |
[2nd] [VARS] -> 6 | (lower, upper, $df$) |
Find probability area under Student's $t$ curve with degrees of freedom $df$. |
Inputs: $p_0$ (null proportion), $x$ (number of successes, must be an integer), $n$ (sample size), prop ($ e p_0, < p_0, > p_0$).
Output: $z$ (standardized test statistic), $p$ ($P$-value), $\hat{p}$ (sample proportion).
Inputs: Data in Lists or Summary Stats ($\bar{x}_1, s_1, n_1, \bar{x}_2, s_2, n_2$), Pooled: Always select NO.
Output: $t$ test statistic, $p$-value, calculated degrees of freedom ($df$).
Always use LinReg(a+bx) (Option 8), NOT Option 4, to conform with College Board notation where $b$ represents slope.
8: LinReg(a+bx).DiagnosticOn, and press [ENTER] twice to display correlation coefficient $r$ and $r^2$.RESID ([2nd] [STAT] -> NAMES -> RESID).Proctors will instruct you to clear calculator RAM before Section I. Practice re-enabling DiagnosticOn and setting RADIAN/DEGREE modes beforehand.
If you calculate $x = n \times \hat{p}$ and get a decimal (e.g., 42.6), you must round to the nearest whole integer (43), or the TI-84 will give a DOMAIN ERROR.
