Experimental Design
Observational Study
In a box plot, this shows that 50% of the data lies on the left and 50% of the data lies on the right
What is Median

There are these many units in AP Statistics
9 Units
In an experiment, what group does not receive treatment?
Control group
Objects that are used for probability
(Answer could be one of the ones listed. If not listed, it is up to host to determine if it's appropriate)
What are, 6 sided dice, playing cards, random number generator, coin flip
Explain the Central Limit Theorem (CLT)
for a large enough sample size, the sampling distribution of the sample mean will be approximately normally distributed
Q3-Q1
This school is cancelling AP Statistics for the school year 2024-2025
XCLASB?
Difference Between Stratified and Cluster Sampling
Stratified takes few from many, while Cluster takes many from few
This is the probability that you land 5 heads in a row
1/2 * 1/2 * 1/2 * 1/2 * 1/2=1/32
Explain Margin of Error
The range of values above and below a sample statistic in a confidence interval
What is the summary measure that is calculated from a sample data set
What is the chance of rolling a six on a dice and getting a 2 right afterwards
1/6 * 1/6 = 1/36
Explain Randomized block design
Subjects are put into similar blocks and randomly assigned treatments within each block
P(A U B)= P(A)+ P(B)-P(A ∩ B)
What is the Addition Rule
A pharmaceutical company is testing a new drug to see if it is more effective than the current standard treatment for a certain disease.
What is an example of a Type I error in this context
Concluding that the new drug is more effective than the current standard treatment when, in reality, it is not.
What percent of the data is at Q3
75%
This is the reason Kyle need to know the probability of getting a 6 and then getting a 2 right afterwards?
(You better had paid attention to the video :))
So he can gamble $_$
Explain different types of bias
* nonresponse
* response
* under coverage
* convenience
For a standard normal distribution, this is the probability that a value falls within one standard deviation of the mean
What is approximately 68%?
A pharmaceutical company is testing a new drug to see if it is more effective than the current standard treatment for a certain disease.
What is an example of a Type II error in this context
Failing to conclude that the new drug is more effective than the current treatment, when in reality, it is
what is thee formula for an outlier test
Get IQR first (Q3-Q1)
Q1-1.5(IQR)=lower outlier
Q3+1.5(IQR)=higher outlier
