Term
statistical null hypothesis 

Definition
specific claim about a population parameter, usually assumes the negative or skeptical point of view (there is no change, unrelated) 


Term

Definition
represents all other possible parameters except the one the null is stating 


Term

Definition
measurable factor that defines or helps define a population 


Term

Definition
inference about a population parameter from sample data 


Term

Definition
specific number or quantity calculated from the data that is used to compare the data gathered to the expected values based on the null 


Term

Definition
calculated from the estimate, it is the distribution of a sampling statistic (e.g. mean) if calculated from many different samples many times 


Term

Definition
is the sampling distribution of outcomes for a test statistic that assumes that the null hypothesis is true 


Term

Definition
probability of obtaining data under the null hypothesis 


Term

Definition
threshold for accepting or rejecting the null based on the pvalue (usually .05) if it is below .05, you reject the null 


Term

Definition
mistakenly rejecting a true null hypothesis. The significance level is the probability of a type 1 error (.05 means 1 in 20 chance, which is acceptable) 


Term

Definition
fail to reject a false null, study with a low probability of type 2 error is said to have a high power. 


Term

Definition
probability that a random sample will lead to rejection of a false null hypothesis
