Unit 1 Key Terms (15-23%): Exploring One-Variable Data

Unit 1 includes the roots of statistics, and it is very important to get these concepts down and memorized. In this unit, you will distinguish between categorical and quantitative data, describe and compare distributions, and begin to learn about normal distributions.

Unit 2 Key Terms (5-7%): Exploring Two-Variable Data

Unit 2 is an expansion of Unit 1. It builds on the relationships between two categorical or quantitative variables and how to argue about the strength between the two. This unit includes a lot of set interpretations of the different components of an LSRL which are very important to remember.

Unit 3 Key Terms (12-15%): Collecting Data

This unit discusses sampling methods and ways of collecting data that can be used to represent a population. It is filled with vocabulary that is essential in future units.

AP Statistics Collecting Data by rachel_thiebout

Unit 4 Key Terms (10-20%): Probability, Random Variables, and Probability Distributions

Everyday, we see things that happen simultaneously to the point we question the possibility of that event happening again. This brings in probability, the proportion of times the outcome would occur in a large number of repetitions. Unit 4 is all about probability and is very calculation heavy.

AP Statistics CB Unit 4+5: Probability, Random Variables, Probability Distributions, Sampling Distributions by Zosia_Stawiarska

Unit 5 Key Terms (7-12%): Sampling Distributions

This unit is an introduction to significant tests, which are covered in later units. It begins introducing statistics, bias, the CLT, and population parameters.

AP Statistics Chapter 7 - Sampling Distributions by Janet_Delery

Unit 6 Key Terms (12-15%): Inference for Categorical Data: Proportions

This unit is the beginning of significant tests, in which you are expected to check conditions, construct and interpret confidence intervals, and calculate a p-value. This unit consists of estimating population parameters involving categorical data.

Unit 6: Inferences for Categorical Data: Proportions by Cfritz15

Unit 7 Key Terms (10-18%): Inference for Quantitative Data: Means

This unit is very similar to Unit 6, but instead of dealing with proportions (p), we are dealing with means (μ). Many of the concepts overlap, but it is important to note that we cannot write proportions anywhere we are running an inference test for quantitative data.

AP Statistics - Inference for Quantitative Data: Means by AlyssaMorales107

Unit 8 Key Terms (2-5%): Inference for Categorical Data: Chi-Squared

Chi-Squared significant tests operate differently than proportion and mean significant tests. 

 χ² distributions are skewed right. The degree of skewness depends on the degrees of freedom.

AP Statistics Chapter 11: Inference for Distributions of Categorical Data

Unit 9 Key Terms (2-5%): Inference for Quantitative Data: Slopes

There is variability in slopes as well. In this unit, you will learn how to perform significant tests and construct confidence intervals about the slope of a regression line.

Best Quizlet Decks for AP Statistics

AP Statistics will probably be more difficult than the other math classes you've taken (besides Calculus 😂) since it doesn't just involve math; it involves analyzing qualitative, as well as quantitative, data! However at the same time, the class is totally doable 💪 Concepts build on each other pretty quickly, so make sure to keep up with the work and ask questions 🤔 if you're confused.

Lots of people, including myself, consider Statistics to be half English and half math! There are whole units that don't have a single equation or an ounce 📐 of math 😱

On the test, you answer multiple-choice questions (MCQs 🧐). The current format is as follows:

Then, you'll answer 6 free-response questions in an hour and 30 minutes. A calculator will be by your side the entire time, so don't worry! Check out these articles to get an idea of the questions you'll see:

Here are the score distributions from 2019 + 2020:

In AP Statistics, the pass rate is generally around 60%! That's pretty good for an AP Exam 🎊

A simple random sample (Unit 3 coming in clutch 🤩) of AP Statistics Fiveable users rated how hard the AP Stats Exam was on a scale from 1 star ⭐ (easy peasy) to 5 stars ⭐⭐⭐⭐⭐ (super hard). Here are the results:

Self-Created Using Microsoft Excel Graphs. This pie chart shows that many students have mixed feelings about how hard the AP Stats exam is. A reassuring factor from this graph is that many students think that it's an average level of hard 👍

The mean rating (that's on one 1️⃣-variable data analysis) for the AP Stats exam was 3.22/5 😂

One of our new initiatives here at Fiveable for the 2020-2021 school year is Fiveable Courses! You can sign up for the AP stats Fiveable course to get access to a bunch of assistance throughout either the fall or spring semester. This can be super helpful — whether you are self-studying or looking for extra support to supplement your in-class work.

It's $55, and it'll be worth it in the long run! 🙂 Sign up for Fiveable's

First, don't just memorize 🧠 formulas and vocab. Try to understand the reasoning behind each concept. There's a large focus on graphing and real-world applications, so make sure to figure out the meaning behind formulas and rules.

Second, brush up on your algebra skills. A lot of times, students will understand the statistics concept part of a question, but they'll make mistakes because of small algebraic errors. Check out this stream: 

Third, practice FRQs! Try to answer questions in the time limit. When you finish, look at the answer key and compare your work. Remember that every time you correct a mistake, you learn something new.

Lastly, let's hear 👂 some words of wisdom from the Fiveable community:

"Break it down! Everything in Statistics is connected; once you make these connections and understand every step, the overall process is easier to understand."—Jane Zhao

"AP Statistics requires determination and resilience because there will undoubtedly be certain aspects that are hard to understand but do not give up! This subject is very broad and can be found in the real world, making it all the more beneficial. So don't give up if you don't grasp a concept quickly. Keep trying!"—Dishitar

"Absolutely worth it!! As someone who loves politics and polling, AP Stats has helped me understand what the heck they mean by margin of error, sample size, and causes of bias! Also, AP Stats is multidisciplinary, applicable in the humanities, social sciences, and STEM!"—Brandon Wu 

All in all, AP Stats is definitely 💯 worth taking. It's extremely useful for most STEM 🧪 fields, like physics, chemistry, and biology. Even if you aren't going into STEM, statistics is a new type of math that you just might like if you try 🙃

If you start to find it difficult, don't get discouraged! You'll come out of the class knowing more than you did before, and Fiveable 5️⃣ has 

Is AP Statistics Hard? Is AP Statistics Worth Taking?

Stagflation refers to an unusual circumstance in economics. 

Imagine the U.S Macroeconomy is in equilibrium as shown below:

Now try to imagine a scenario where the equilibrium price has increased while the equilibrium quantity has decreased. Have you ever thought about it before? 

Well, this is what you call a situation of 

Stagflation refers to when the economy suffers from persistent high inflation and high unemployment. 

Still not sure how stagflation relates to the scenario mentioned above? Well, here is a graph of stagflation: 

When the Aggregate Supply of the economy decreases, the equilibrium quantity of goods and services purchased decreases and their equilibrium price increases. 

When the equilibrium quantity in a macroeconomy decreases, less workers are needed to produce those goods and services

The Aggregate Demand for goods and services has remained the same while the Aggregate Supply has decreased. 

This results in consumers bidding for a lower supply of goods and services, leading to an increase in the equilibrium price of the goods 

Thus an increase in the rate of inflation occurs 

This means that the value of currency has decreased.

At the end of the day, Stagflation benefits absolutely nobody, for high unemployment coupled with high inflation is a nightmare for both producers and consumers of goods and services. Use this knowledge and practice

I'm an AP Stats teacher and streamer at Fiveable. This year's exam is different than we expected, but I'm here to help. I've put together this study guide to help keep you on track while you are studying from home.

 I'll also be joining a group of students live on Mondays @ 9pm ET during cram sessions. 

🎓This guide is from the Spring 2020 exam season. For Fall 2020, check out the 

 for self-study, homeschool, or supplemental learning. 

This year, the AP Statistics exam will look different than you were expecting. As we’re all on quarantine 😷 due to COVID-19, the College Board has decided to update the format and content of the test to fit an online testing format.

You’ll have 45-minutes to take the exam online and it will only cover units 1-7. If you have already studied content from unit 8 or 9, don’t stress! It’s all worth knowing.

Exploring One-Variable Data
2 - ✌️ Exploring Two-Variable Data
3 - 🔎 Collecting Data
4 - 🎲  Probability & Random Variables
5 - 📊  Sampling Distributions
6 - ⚖️ Inference for Categorical Data - Proportions
7 - 😼  Inference for Quantitative Data - Means

8 - ✳️ Inference for Categorical Data - Chi-Square

9 - 📈 Inference for Quantitative Data - Slopes

Wherever you are in the world, this is the time you’ll take the test. Unless you have been approved for the make-up date in June, but only your school can request that. You’ll take the test online. There will be a practice simulation posted by College Board within the next few weeks.

With so many school closures and the stress of a global pandemic, this review season will be different than usual. If this is your first AP exam, welcome! Don’t worry, it’s not usually this chaotic. 

We’ve put together this plan for you to follow between now and May. This will cover all of the units and leave you time to practice questions before test day. Some classes may have done units out of chronological order throughout the year, which is ok. The units don’t have to be taught in order. If you are learning new material on your own and need some help, use the chat bubble on 

. We’ll answer any questions you may have. 

All of the required resources are free, including the AP stats cheat sheet. 

  We’ve also linked a few other websites, articles, and YouTube videos that you can access for free. Some of the suggested resources include paid products. There are some documentaries that you can find on streaming sites with a paid membership and we’ll also list streams and practice questions that require a paid cram pass on Fiveable.

Before we begin, take some time to get organized. Remote learning can be great, but it also means you’ll need to hold yourself accountable more than usual. 

Make sure you have a designated place at home to study. Somewhere you can keep all of your materials, where you can focus on learning, and where you are comfortable. Spend some time prepping the space with everything you need and you can even let others in the family know that this is your study space. Claim your territory by printing out and posting your AP stats cheat sheet PDFs! We at Fiveable don't love that term, but our creators have lovingly crafted these 1 page 

Get your notebook, textbook, prep books, or whatever other physical materials you have. Also create a space for you to keep track of review. Start a new section in your notebook to take notes or start a Google Doc to keep track of your notes. Get your self set up!

The hardest part about studying from home is sticking to a routine. Decide on one hour every day that you can dedicate to studying. This can be any time of the day, whatever works best for you. Set a timer on your phone for that time and really try to stick to it. The routine will help you stay on track.

How will you hold yourself accountable to this study plan? You may or may not have a teacher or rules set up to help you stay on track, so you need to set some for yourself. First set your goal. This could be studying for x number of hours or getting through a unit. Then, create a reward for yourself. If you reach your goal, then x. This will help stay focused!

Unit 1 is about creating and analyzing graphs of data. This includes both categorical and quantitative data. For categorical data, we should be able to read and create tables and bar graphs, and calculate proportions/percentages. For quantitative data, we should be able to read and create dotplots, stemplots, histograms, and boxplots. We should also be able to describe the shape, center, variability (spread), and any unusual features of a distribution of quantitative data. This includes making calculations such as mean, median, range, interquartile range (IQR), and standard deviation. Our descriptions and calculations can be used to compare data from multiple groups. Finally, Unit 1 ends with describing the position of individuals within a quantitative data set, including using percentiles and z-scores. This leads us to an initial exploration of the Normal Distribution, though we will study that more in-depth in Units 4-5.

If you have more time or want to dig deeper:

✌️ UNIT 2: Exploring Two-Variable Data

Unit 2 is about creating and analyzing graphs of data when two variables are measured about each individual in a data set. For categorical data, we should be able to read and create two-way tables or segmented bar graphs, and calculate conditional percentages. These can be used to comment on the association (or lack thereof) between the two variables. For quantitative data, we should be able to read, create, and describe scatterplots, which can also be used to comment on apparent association between two variables.

The second half of Unit 2 is then focused on linear regression, a process by which we can make predictions about one quantitative variable (a response variable) using another (an explanatory variable). We should be able to use Least-Squares Regression Lines to make these predictions, and interpret several components of the LSRLs (including slope, intercept, and other calculated values such as s or r2)

While Units 1-2 were about graphing and analyzing sets of data, Unit 3 is about examining the methods through which we can collect that data. For sample surveys, we should be able to describe various methods of selecting samples, particularly the random methods (simple random, stratified random, cluster, and systematic samples). However, not all samples are collected through a random process, and we should be prepared to discuss possible sources of bias in surveys (including via non-random selection processes).

We then turn to the differences between observational studies and experiments, and the features of a well-designed experiment. We should be able to define many common terms associated with experiments (many of which you’ve likely seen in other courses!), and compare and contrast several common experimental designs: completely randomized design, randomized block design, and matched-pairs design.
