Statistical Significant Test

process that uses sample statistics to test a claim about a population parameter

• null hypothesis

• alternative hypothesis

• statistical hypothesis

• hypothesis test

if the null is rejected when it is actually true

• Level of Significance

• Type 1 Error

• Type 2 Error

• p value

assumes the null is true and is the probability of getting a sample statistic this extreme

• Level of Significance
