The proportion of times the outcome would occur in a very long series of repetitions.
What is Probability
100
Consists of the smallest observations, first quartile, median, third quartile, and the largest observation
What is the five number summary
100
Deliberately imposes some treatment on individuals in order to observe their responses
What is Experiement

You are on a game show there are three doors. Behind one door, is a new car. You take your pick of door number 2. The game show host opens door number 1. There is no car behind door number 1. He then asks you if you would like to change your first guess of door 2. What should you do and what is the probability of the event that you choose being correct.
What is changing to door number 3? There is a 66% chance you will get it right. If you change to door number 3.

Value of a statistic varies in repeated random sampling
What is Sampling Variability?
300
a scatter plot of the regression residuals against the explanatory variable
What is Residual Plot?
300
Control, randomization, replication
What is Basic principles of statistical design?

300
Fail to reject Ho when Ha is true
What is a Type II Error?
400
The simultaneous occurrence of two events
What is Joint Events?

This model becomes linear when you take the log of both variables.
What is Power Model?
400
Divide population into groups of similar individuals (strata) then taking one SRS per group.
What is Stratified Random Sample?
400
How do you increase Power?
What is Increase sample size, decrease standard deviation, raise significance level and spread Ha and Ho far apart.
400
The reversal of the direction of a comparison or an association when data from several groups are combined to form a single group.
What is Simpson's Paradox
500
If two events (A and B) have no outcomes in common, so they can never occur simultaneously what are they described as?
What is Disjoint?
500
Pattern of variation - tells us what values the variable takes + how often it takes these values.
What is Distribution?
500
You want to do Statistical Inference about gerbils in a pet shop. You monitor what each gerbil eats. If the parameter is what is eaten by each gerbil what kind of study have you conducted?
What is a Census/observational study?
500
In an SRS of size n from any population - when n is large the sampling distribution of the sample mean (x̅ ) is close to the normal distribution N (μ,σ/√n) with mean μ and σ of σ/√n
What is Central Limit Theorem?
500
P(A or B) = P(A) + P(B) - P(A and B)
