Neither the subject nor those who measure the response variable know which treatment a subject received.
What is a double-blind experiment?
How to identify outliers for one variable (univariate) data
What is Q1 - 1.5(IQR) and Q3 + 1.5(IQR)?
Find 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) = P(4)^3
(1/6)^3=.005
The correlation coefficient between data sets in L1 and L2
What is STAT-->CALC-->8:LinReg(a+bx) L1, L2?
A common form of blocking for comparing two treatments. (and which requires a One Sample T-Test for inference)
What is matched pairs?
How do you find the expected value of a discrete random variable?
Take the mean of the random variable -- found by summing the products of the values of x and their respective probabilities.
The rule for the probability of pulling a red or queen from a standard deck of cards.
What is P(red or queen) = P(red) + P(queen) - P(red and queen)
(26/52)+(4/25)-(2/52)
What is notion/rule for finding the probability of selecting a Senior, given that they are an AP Stats student
What is
P(Senior|AP Stats Student) =
P(Senior AP Stats Student)/P(AP Stats Student)
The area under the normal curve below positive 2 standard deviations.
What does InvNorm tell us?
What Z value corresponds to a certain area under the curve.
The rule for finding the probability of obtaining the first success on the 4th trial with a 25% success rate.
geometrpdf(.25, 4)
The chi-squared test statistic with observed values in L1 and expected counts in L2
What is (L1-L2)^2/L2-->L3 then sum(L3), OR x^2GOFTest(L1, L2, n-2)
The mean and standard deviation of the sampling distribution of sample means
The standard deviation of the sampling distribution of sample means is equal to the population standard deviation divided by the square root of the sample size? aka ΓΈ/sqrt(n)
T he mean is equal to the mean of the population
How do you find the probability of 10 or fewer successes in 15 trials, when P(success)=0.5
BinomCDF(15, 0.5, 10) = .94
