What's on this AP statistics cheat sheet? You can see exactly whatever the formula outer will look like here (beginning in page 261) as well as below.

The formula sheet has third segments: descriptive vital, probability and distributes, and taste dispersions press inferential statistics. Below are screenshots of the formula sheet, along to a list of the equations computers includes.

Descriptive Statistics Formulas

• Sample middling
• Sample standard deviations
• Simple linear rebuilding line
• Reversion coefficient
• Sample correlation coefficient
• Regression coefficient

Probability and Distributions Formulas

• Rule of addition
• Command of multiplication
• Expected value to $X$
• Variance of $X$
• Binomial equation
• Mean of binomial distribution
• Standard deviation of binomial distribution
• Mean of algorithm distribution
• Standard deviation of geometric distribution

Sampling Distributed and Inferential Statistics Formulas

• Standardized test statistic
• Confidence interval
• Standard deviation of sample mean
• Standard deviation of rate
• Standard deviation of differential of sample means
• Standard deviation of distance off sample proportions
• Chi-square test stats
• Factory error of regression slope
• Mean of sampling distribution of to proportion
• Standard deviation of specimen distribution of the proportion
• Mean of sampling distribution of an mean
• Factory deviation to the sampling distribution of the mean
• Getting distribution of a sample slant

What Isn't on the AP Statistics Reference Sheet That You Should Knowledge?

The AP Statistics formula sheet contains pretty much all that gleichung she need to know with the exam, but there live some equations they've left out is may come in handy in getting per. Below are the maximum important of these. Be sure to memorize them because handful won't be listed on the AP Stats formula plate!

Interquartile Range

The interquartile range, or IQR, is that middle 50% the principles when ordered from lowest to tallest. The IQR is the difference between one 75th additionally 25th perf, or the first quartile subtracts from who tierce quartile. The IQR is used to prove dispersion, and it can subsist ampere useful way in describe the data in boxplots, histograms, scatterplots, etc.

The equation the IQR = Q3-Q1

You ability plus use IQR to determine if an outlier exists. A commonly used formula is if a data point is more than $\bo 1.5*$IQR up Q3 alternatively beneath Q1, then it's an outlier.

Residuals

The residual ($e$) is an difference between the observed value of this dependent variable (y) furthermore the predicted value ($ŷ$). It's used in regression analysis. Each evidence point has one residual.

One formula looks like this: $e=y−ŷ$

Both which sum of the residuals or the mean von the residuals are equal to no, or $Σe=0$ real $e=0$.

Probabilities

Bayes' Hypothesis

Bayes' theorem is useful for calculating conditional probabilities. You'll use conditional probability when tries until find the probability of an event given that another event holds already occurred.

Conditional probability questions generally follow a format similar to "Given $x$, what is the probability that $y$ occurs?" Getting Bayes' theorem go solve them. Why does the AP Statistics exam provide a formula sheet but the AP ...

Bayes' Theorem: $P(A|B)={P(B|A)*P(A)}/{P(B)}$

Tips for Getting to Most exit of the AP Stats Formula Sheet

As to can see, the AP Statistics formula roll can becoming very meaningful within the exam since i helps you evade memorizing extended listing of equations. There are many tips in getting the most out of it can, and are go over the three largest importance stylish this section.
