Yes—calculator use is expected on both sections of the AP Statistics Exam. In 2027, you can use the built-in Desmos graphing calculator in Bluebook and may also bring permitted handheld calculators. The calculator can compute; your score still depends on choosing the right procedure, checking conditions, and interpreting the output in context.
This guide separates current College Board exam-day policy from calculator features that still exist but were removed from the revised AP Statistics course. Exact handheld approval is model-specific and should be rechecked shortly before the May 2027 exam.
Can I use this calculator on the AP Statistics Exam?
Choose the calculator or technology you plan to use. This checker separates the built-in Bluebook Desmos calculator, approved handheld graphing calculators, and devices that are prohibited for the 2027 AP Statistics Exam—including nongraphing calculators.
Select a device above. For handheld graphing models, the controlling rule is the current College Board approved-calculator list, which can be updated before exam day.
The current official graphing-calculator list includes common families such as TI-84 Plus/CE, many TI-Nspire models, Casio FX-CG-50, HP Prime, and NumWorks. Recheck the exact model before May 2027 because the list can be updated.
College Board’s 2027 AP Statistics update explicitly prohibits nongraphing calculators, even models with the statistical capabilities required for the course. Use Bluebook Desmos and/or an approved handheld graphing calculator.
The web-based or standalone Desmos app may be useful during the school year, but on the AP Exam the permitted Desmos is the calculator built into Bluebook.
Bluebook Desmos or TI-84: which should you use?
You do not have to choose only one. The strongest plan is to use the tool you already operate accurately under time pressure and know the Bluebook Desmos route well enough to serve as a second pathway.
Find the right calculator workflow before you press buttons
Select the statistical task. The guide returns a TI-84 route, a Desmos route, the input structure, and the piece of statistical writing the calculator cannot do for you.
Put quantitative observations in a list, then run 1-Var Stats on that list. Read x̄, Sx, n and the five-number summary.
Store observations in a list or table. Desmos can summarize the data and display sample standard deviation and five-number summary.
Do not report Sx as a population standard deviation unless the data are actually the entire population.
Name the statistic and explain what it says about the data in context. Calculator output alone is not a statistical conclusion.

The calculator skills that matter for AP Statistics in 2027
A strong calculator guide should match the revised course, not recycle an old command sheet. The highest-value workflows now cluster around data summaries, probability, proportions, means, chi-square association, and regression analysis.
1-variable summaries
n, mean, sample standard deviation, quartiles, IQR, outliers, histograms and boxplots.
Calculator job: summarize accurately. Your job: discuss shape, center, spread and unusual features.Normal models
Normal cumulative probabilities, inverse normal percentiles, standardized values and probability interpretation.
Calculator job: area or cutoff. Your job: connect it to the random variable and units.Binomial models
Exact-count and cumulative binomial probabilities after checking binary outcomes, fixed trials, independence and constant probability.
Do not skip conditions.z intervals & tests
One- and two-proportion confidence intervals and hypothesis tests, with different standard-error logic for intervals versus null tests.
t intervals & tests
One-sample, paired-difference and two-sample t procedures. Pairing is a design issue, not a calculator menu preference.
Chi-square association
Expected counts, chi-square statistic and inference for homogeneity or independence using a two-way table.
Least-squares line & r
Fit a linear model, obtain correlation, make predictions and calculate residuals. Interpret slope and residuals with units.
x̄ and p̂ models
Use the correct center and standard error for a sample mean or sample proportion, and verify the independence/shape conditions before using a Normal approximation.
Expected value & SD
For a discrete probability distribution, calculate the long-run mean and spread from outcomes and their probabilities; verify that probabilities form a valid distribution first.
Simulation
Random-number generation can support probability and sampling reasoning, but the simulation design still has to mimic the chance process correctly.
Old calculator cheat sheets can send you to removed AP Statistics topics
The revised 2026–27 course removed the geometric distribution, chi-square goodness-of-fit, inference for a regression slope, combining random variables, and analyzing departures from linearity. A calculator may still contain commands for some of these topics; that does not make them current AP Statistics core content.
Why this matters: several otherwise useful calculator guides still teach geometric or chi-square goodness-of-fit because the calculator continues to support those commands. This page filters calculator capability through the revised 2027 AP Statistics framework.
Calculator rules students actually need to know
The most important rules are short. They should be visible before a giant practice bank or device tutorial.
Know one calculator deeply
Do not switch to a new model during exam week because it has more features. Familiarity beats menu hunting.
Bring a legal backup
If you rely on a handheld, a second permitted model can protect you from battery or hardware failure.
Practice Bluebook Desmos too
The built-in calculator gives you a second pathway. Learn lists, distributions, inference tools and regression before May.
Recheck the official list
Approval lists can be updated. Reconfirm your exact graphing calculator model shortly before the 2027 administration.
What calculator output does not write for you on an FRQ
Many calculator pages stop at button sequences. AP Statistics does not. The scoring value comes from connecting technology to a defensible statistical argument.
Do not write only “reject H₀.” State the significance comparison and conclude about the population parameter in the problem context.
Identify the parameter and confidence level, then interpret the interval as plausible values for that population quantity.
Interpret slope using response units per one unit of the explanatory variable. Association is not automatically causation.
Check expected-count conditions and link the decision to evidence of association/difference in the categorical setting.
Six calculator mistakes that create wrong AP Statistics answers
Read the input labels. A test that asks for x and n wants integer successes and sample size, not p̂ and n.
The calculator follows your alternative. Translate “greater than,” “less than,” and “different from” before opening the test menu.
For sample data used to estimate a population spread, sample standard deviation is usually the relevant statistic.
For matched pairs, calculate differences first and analyze the single list of differences with a one-sample t procedure.
Correct arithmetic cannot rescue an invalid procedure. Randomness, independence, counts/shape and design requirements still matter.
Geometric, chi-square goodness-of-fit and regression-slope inference are no longer core topics in the revised AP Statistics framework.
Use the calculator page for calculator decisions and workflows
Score conversion, exam format and full-length practice belong on their own pages. This prevents one giant AP page from trying to rank for every query.
AP Statistics calculator FAQs
Can you use a calculator on the AP Statistics Exam?
Yes. College Board lists calculator use as expected for both the multiple-choice and free-response sections of AP Statistics.
Will Desmos be available on the 2027 AP Statistics Exam?
Yes. The fully digital 2027 exam is completed in Bluebook, and the built-in Desmos graphing calculator is available. The ordinary Desmos website or separate app is not what students use during the exam.
Can I bring a TI-84 Plus CE?
The TI-84 Plus CE family appears on the current College Board list of approved handheld graphing calculators. Because that list can be updated, recheck the exact model before the May 2027 administration.
Can I bring two calculators?
Yes. Current College Board policy allows up to two permitted handheld calculators in addition to the built-in calculator available through Bluebook.
Do calculator memories have to be cleared?
No. Current College Board policy says calculator memories do not need to be cleared before or after the exam.
Can I use a scientific or nongraphing calculator instead of a graphing calculator in 2027?
No. Beginning with the 2027 AP Statistics Exam, College Board says nongraphing calculators are not allowed, even if they have the required statistical computational capabilities. Use the built-in Bluebook Desmos graphing calculator and/or an approved handheld graphing calculator.
Do I still need to show work if the calculator gives the answer?
For free response, statistical reasoning matters. You need to identify the procedure, satisfy relevant conditions, report appropriate results and interpret them in context. A screen value alone is not a complete response.
Should I learn geometric distribution or chi-square goodness-of-fit calculator commands for 2027?
They are not priorities for the revised AP Statistics core. The geometric distribution and chi-square goodness-of-fit were removed from the 2026–27 course framework.
Use the calculator to compute. Use statistics to earn the points.
For 2027, know Bluebook Desmos, know your permitted handheld, and practice the revised-course procedures until the calculator is a fast tool—not a substitute for method selection or interpretation.
Practice by revised topicKnow what the calculator can do—and what you still must decide
Calculator fluency helps only after the statistical method is justified. This crosswalk is designed for the 2027 course: it keeps the device action separate from the reasoning you must supply in a multiple-choice decision or typed free-response explanation.
| Task | Typical TI-84 route | Bluebook Desmos route | Reasoning you still own |
|---|---|---|---|
| 1-variable summary | 1-Var Stats | stats / list summaries | Choose resistant vs nonresistant summaries and interpret shape/spread. |
| Normal probability | normalcdf | normal distribution CDF | Identify μ, σ, bounds, and what probability means. |
| Normal percentile | invNorm | inverse normal / quantile | Translate percentile to area correctly. |
| Binomial | binompdf / binomcdf | binomial distribution | Verify fixed n, two outcomes, independence, constant p. |
| Regression | LinReg | regression expression | Interpret slope, r², residuals, and avoid causal language without design support. |
| 1-proportion inference | 1-PropZInt/Test | proportion inference functions | State parameter/hypotheses, conditions, and conclusion. |
