The probability of winning the lottery is 50%, you either win or you don't
Mom, am I normal?
Correlation does not mean Causation
From the reading
100

This phrase is used to describe an observed effect so large that it would rarely occur by chance.

What is statistically significant? 

100

This type of random variable requires a fixed number of trials, each observation to be independent, and to have two outcomes ("success" or "failure").

What is a binomial random variable? 

100

This calculator command can be used to find the area under a normal distribution and above an interval.

What is normalcdf? 

100

How to identify outliers for one variable data.

What is Q1 - 1.5(IQR) and Q3 + 1.5(IQR)? 

100

The likelihood of a significance test detecting an effect when there actually is one.

What is statistical power? 

200

The type of significance test used for the mean of a single population when the standard deviation of the population is unknown. 

What is a T test? 

200

Events that have no outcomes in common and can never occur simultaneously, for which the addition rule is used. 

What are disjoint events (or mutually exclusive events)? 

200

This rule helps to determine if data is normally distributed by checking the number of observations within 1, 2, and 3 standard deviations away from the mean.

What is the Empirical Rule (68-95-99.7 Rule)? 

200

Neither the subject nor those who measure the response variable know which treatment a subject received. 

What is a double-blind experiment? 

200

Rejecting the null hypothesis of no effect when it is actually true.

What is a Type I error?

300

The three conditions needed for a z-test. 

What are the random condition, 10% condition, and large counts condition? 

300

The probability of rolling a fair die three times and getting three fours. 

What is P(rolling three 4s) = P(4)*P(4)*P(4) = 1/216

300

This measure of center is more resistant to outliers than the mean. 

What is the median? 

300

The 3 basic principles of experimental design.

What are control, randomize, and replicate? 

300

Usually set at 5%.

What is significance level?

400

The interpretation of the p-value of 0.001 given an alpha = 0.05. 

What is "since the p-value is less than alpha = 0.05, we reject the null hypothesis, and conclude there is significant evidence to support the alternative hypothesis"?

400

The probability of pulling a red or a Queen from a standard deck of cards. 

What is P(red or queen) = P(red) + P(queen) - P(red and queen)  = 28/52

400

The square of the standard deviation

What is the variance? 

400

When some groups in the population are left out of the process of choosing a sample.

What is undercoverage bias? 

400

Not rejecting the null hypothesis of no effect when it is actually false.

What is a Type II error?

500

The 95% confidence interval (-4.25,-1.33) for the difference of two means (mean #1 - mean #2). 

What is "We are 95% confident that the true difference of means, mean #1 - mean #2, is between -4.25 and -1.33"?

500

The rule for finding the probability of a female given that they are an AP Stats student. 

What is P(Female|AP Stats Student) = P(Female AP Stats Student)/P(AP Stats Student)?

500

To calculate, subtract the mean of the distribution from the observed x, then divide by the standard deviation. 

What is the z-score (or standardized value)? 

500
The population is divided into groups. Some groups are randomly selected and all individuals in the chosen groups are sampled. 

What is cluster sampling? 

500

the magnitude of a difference between groups or a relationship between variables.

What is Effect Size?
