Probability
The complement of p = 0.2, also known as p'
or a complement for someone named "Zero Point"
what is 0.8?
the b in ŷ = a + bx
What is the slope?
The ideal sampling method, it could be described as holistic . . .
What is a census?
These measures of center become aligned in a Normal Distribution, just like the stars will on May 7!
What are the mean and median?
What is a Type I Error?
These two events cannot occur at the same time, it's not a one-sided beef, though, this feeling is shared!
What are mutually exclusive events?
Don't be naive! ChatGPT loving your singing, Ms. Fedenko's email invitation for free furniture, and a pattern showing up on this aren't good things!
What is the residual plot?
This sampling method involves dividing a population into smaller, homogenous groups and randomly selecting a few of these groups at a time, you might as well throw in candy for their time . . .
What is cluster sampling?
The Central Limit theorem is very forgiving even if your population is horribly skewed. Samples taken from a skewed population are Normally distributed as long as they are this size
What is 30?
The value to check the p-value against
or the artist credited for La mamá de la mamá . . .
What is the significance level or alpha?
The operator used to find the probability that two events occur simultaneously
Hold your horses! This procedure might imply you have a negative GPA or that your grandma has superpowers and should be avoided at all costs!
What is extrapolation?
Is the new Michael movie really that good, or are people just really big fans of watching a 2 hour music video playlist? Michael Jackson's fame is an example of this annoying effect that is ruining my experiment!
What is a confounding variable?
This type of significance test compares two or more datasets to see if they are distributed in the same way
If the datasets are different, one is probably just making sure they don't fit in . . .

What is a Chi-Squared Test for Homogeneity?
t-distributions use these in order to work. They're easy to miscount, so be careful!
The output of the function used at the beginning of the formula for the binomial distribution, read as "from n choose x"
What are combinations?
This value is basically meaningless when the explanatory variable cannot be 0
In some words, it can sound-less too?
What is the y-intercept or a?
In an experiment, this group is not given a treatment
What is the control group?
If you really want to predict the future you can construct a 100% confidence interval, but your interval might have this (small) problem . . .
What is an impossibly large interval?
The general form of a z-score, this value is needed when performing a significance test by hand.
What is a standardized test statistic?
A series of independent trials, each with a constant probability of success is repeated until a success is recorded and follows this probability distribution.
What is the geometric distribution?
Checking the conditions for inference for the slope of a regression line, this must be true at each value for the input
What is equal standard deviation?
An experiment that usually involves twins randomly being assigned two treatments
What is a matched pairs design?
In 1907, to prevent releasing information that could help their competitors, Guiness told its employees that they couldn't publish work using their own name, so William Gosset's t-test now goes by this name
What is Student's t-test?
The ability for a significance test to "detect" a cuckoo bird. It can be calculated by subtracting beta from 1
What is power?
