Is unpredictable in the short run, predictable in the long run
What is probability?
Two events that cannot happen at the same time
what is mutually exclusive?
the statistics symbol for AND
What is an upside down U ? stands for intersection
this is what type of question "how long do you wait for lunch each day?"
what is a statistical question ?
the Beyone song we used as part of our sampling lesson
What is Crazy in Love

What is non response bias?
Who is player 2

What is a Two Way Table
P(A^c) or "P(A raised to the lower case c)
What is the complement of A ?(meaning A did not happen)
This is what type of study, no treatment, just collecting data
what is an observation study ?
This bias happens when students lie about cheating on a test (when they received an email from the Principal's survey about whether they cheated on a test)
what is response bias ?
we use this "statistics law" to get a more accurate prediction
what is The Law of Large Numbers ?
The name of the formula used when determining the probability of 2 events, you add both probabilities and then subtract the "overlap" to avoid a double count
What is the General Addition Rule?
P (A or B) = P(A) + P(B) - P (A and B)
the | sign in P(A) = P (A | B) stands for...
What is "given"?
What is an experiment study ?
DOUBLE JEOPARDY: The specific condition applied in an experiment
What is the treatment?
In the lesson on probability, trains arrived on time 90% of the time, how could you use a 10 sided dice to perform a simulation ?
roll the 10 sided dice, if a 1 come up, the train is late, if 2-10 comes up, the train is on time.
The statistic rule this formula is showing:
Probability (Player 1 wins) = 1 - Probability (Player 2 wins)
What is the complement rule ?
In our recent lesson, TT and EE stood for ...
