200
an inactive or fake treatment that has no effect on the explanatory variable
Placebo

Here is a 5# Summary:
3, 7, 15, 20, 23
Find the IQR
IQR = 20 - 7 = 13

What type of sampling method is being used?
Survey every 5th person who leaves the grocery store
Systemic

Histogram

P(E OR F) = P(E) + P(F) - P(E AND F)
Addition Rule
400
when the participants do not know which treatment a subject is recieving
Blinding

Given the following data set:
{5, 5, 7, 2, 4, 9}
What is the mean?
barx = (5+5+7+6+4+9)/6 = 36/6 = 6
600
______ data is counted in whole numbers and ______ data is measured (can result in decimal values)
Discrete; Continuous
600
These values divide a data set into four equal parts (quarters)
Quartiles
600
P(E AND F) = P(E) x P(F|E) *dependent events
OR
P(E AND F) = P(E) x P(F) *independent events
Multiplication Rule
600
The group in an experiment that recieves an inactive treatment and is monitored exactly as the other groups
Control Group
600
Given the following data set:
{55, 40, 50, 60, 45}
Estimate the standard deviation
{40, 45, 50, 55, 60}
sigma = 5
800
a number that falls between 0 & 1 and described the likelihood of a specific event occuring
Probability
800
This value described the average distance from the mean
* Hint:
sigma=sqrt((sum (x i - mu)^2)/N
Standard Deviation
800
Two events are known to be ______ if the occurence of one event has no effect on the occurance of another event
Independent
800
the dependent variable; the outcome that is measured for any changes at the end of an experiment
Response Variable
800
At this one stoplight, there is a 5% chance that a car turns left and there is a 35% chance that a car will turn right.
What is the probability that a car will turn left and right?
Trick question! It is impossible to turn left and right at the same time!
So...
P(Left AND Right) = 0!!!
1000
a ________ is a characteristic that described the population and a _________ is a characteristic that described the sample
Population; Statistic
1000
Even though both measure the center of data set, the _______ describes the average value in a data set, but the _______ divides the data set in half
mean; median
1000
Two events are known to be _______ ________ if the chances of them occuring at the same time is zero
*Hint: This question technically has two answers, I will accept both
Mutually Exclusive OR Disjoint
1000
the independent variable; a value that is controlled and affects the outcome
Explanatory Variable
1000
P(Female or A) =
P(Female) + P(A) - P(Female AND A) =
35/70+23/70-3/70= 55/70
