Probability
Two event outcomes that can't happen at the same time?
What is Mutually exclusive event
The method that any sample size has the same chance to be chosen?
What is Simple random sample(SRS)
The claim that we weigh evidence against in a significance test is called a?
What is a Null hypothesis
This graph distribution has one peak and looks roughly symmetrical, often called a “bell curve”
What is Normal distribution
A statistical method that is used for a model to show the relation of two quantitative variables
What is Regression
When two events happen and are not affected by each other's probability?
what is Independent events
Selecting people that use computers and leaving out people that have an ipad?
What is Undercoverage bias
The claim that we are trying to find evidence for is the?
What is a Alternative hypothesis
In this distribution, most of the data is clustered on the left while the tail stretches out to the right
What is Right-skewed
A observed Y and a predicted y has a value of x?
What is Residual
The possible value for a radon variable and its probabilities
What is Probability distribution
When a group of teens don't respond back to their gmail it is?
What is Nonresponse
Probability of getting evidence for the alternative hypothesis as strong or stronger than the observed evidence when the null hypothesis is true
What is the p-value of a test?
A graph with two distinct peaks is described using this term
What is Bimodal distribution
A variation explained by an independent variable
What is Coefficient of determination
Probability that an event occurs given that another event occurs?
What is Conditional probability
Students being put into groups based on their similarities?
What is Stratified Sampling
Value that is used as a boundary for deciding whether an observed result is unlikely to happen by chance alone when the null hypothesis is true.
What is the significance level of a test?
In this type of distribution, data points are spread fairly evenly across all values with no obvious peak
What is Left-skewed
A variable used to predict/explain another variable
What is Explantory variable
A and B, P(A and B) for independent events equals?
What is P(A) x P(B)
randomly selecting a starting point and selecting the individual down the list is?
What is Systematic Sampling
Occurs when we reject null hypothesis when null hypothesis are true. That is, the data give convincing evidence that the alt hypothesis is true when it really isn't.
What is a type I error?
Looking at the histogram, most students scored high on the test, but a few low scores create a long tail on the left side. What type of distribution is shown?
What is Left-skewed distribution
The method to find the “line of best fit” for a set of data points
What is least-square regression
