100
It systematically favors certain outcomes.
What is biased.
100
y axis; measures outcome
What is response variable?
100
A variable tells us what values the variable takes and how often it takes these values.
What is distribution
100
A variable whose value is a numerical outcome of a random phenomenon
What is a random variable
100
a number that describes the population
What is parameter
200
Deliberately imposes some treatment on individuals in order to observe their responses.
What is an experiment.
200
x axis; explains outcome
What is explanatory variable?
200
In any graph of data is an individual observation that falls outside the pattern of the graph.
What is outlier
200
Calculates the sum of the probabilities for 0,1,2,3
What is CDF
200
a number that describes the sample
What is statistic
300
Has outcomes that we cannot predict but that nonetheless have a regular distribution in very many repetitions.
What is random phenomenon.
300
Straight line, describes response variable, y changes as an explanatory variable changes
What is least square regression?
300
The right and left sides of the histogram are approximately mirror images of each other.
What is symmetric
300
a distribution that lists the values and probabilities
What is probability distrubution
300
a distribution of values taken by the statistic in all possible samples of the same size from the same population
What is sampling distribution
400
The proportion of times the event occurs in many repeated trials of random phenomenon.
What is probability.
400
Changes in X cause change in Y
What is causation?
400
The normal distribution with mean 0 and standard deviation 1.
What is standard normal distribution
400
a random variable that takes all values in an interval of numbers
What is continuous random variable
400
provides methods for drawing conclusions about a population from sample data
What is statistical inference
500
Set of all possible outcomes. S={ }
What is sample space.
500
Use of regression line for prediction far outside the domain of values of the explanatory variable X that you used to obtain the lien or curve.
What is extrapolation?
500
A variable plots each observation against the time at which it was measured.
What is time plot
500
describes the probability distribution of a continuous random variable
What is density curve
500
gives the probability that the interval will capture the true parameter value in repeated samples
What is a confidence level C
