This value measures the strength of a relationship.
What is the correlation value (r-value)?
100
This represents an overall effort to minimize variability in the way experimental units are obtained and treated.
What is control?
100
The sum of the probability of all possible outcomes must equal this value.
What is 1?
100
This term is used to describe the probability of random variables.
What is probability distribution?
200
An r-value very close to 0 indicates a ________ relationship.
What is weak?
200
This treatment is also known as a "dummy" treatment.
What is a placebo?
200
The Probability of A and B, or P(A and B), equals this.
What is P(A) x P(B)?
200
This type of average is found by multiplying each possible value of "x" by its probability, then adding all of the products.
What is the weighted average, or mean of a discrete random variable?
300
This value determines whether or not a model is appropriate to represent a relationship
What is the coefficient of determination?
300
In this type of experiment neither the subjects nor the people interacting with them know which treatment is given to each treatment group.
What is a double-blind experiment?
300
The probability of A occurring GIVEN B equals this.
What is the probability of A and B occurring divided by the probability of B, or P(A and B)/P(B).
300
This value is determined by taking the square root of the variance.
What is standard deviation?
400
This value truly means that for every change in one unit of x, the response variable will change M units.
What is the slope of a regression line?
400
This type of sampling strategy involves dividing the population into groups of individuals that are similar in some way that is important to the response.
What is stratified random sampling?
400
This type of table can be used to display the following data:
A Spanish class consists of 15 seniors and 3 juniors, of which 10 are males and 8 are females.
What is a two-way table?
400
This type of variable takes all values in an INTERVAL of numbers.
What is a continuous random variable?
500
This equation represents the residual, or predicted error.
What is the observed value - predicted value?
500
An example of this type of experiment is when one experimental unit gets BOTH treatments one after another.
What is a matched pairs design?
500
A survey is done on students who drink either coffee, tea, or coffee AND tea. 50% of students said they drink coffee , and 25% said they drink both tea and coffee. This number represents the percentage of students that drink tea.
What is 50%?
500
This term is represented by the expression 1 - P(X), or one minus the probability of x.
