Type I Error
occurs when you reject the null hypothesis during a hypothesis test when it is true
Type II Error
occurs when you accept the null hypothesis when it is not true
1- Sample T Test Sample size Calculation
-means testing -comparing a target value -already have sample statistics about the population
1-Sample Z Test Sample Size Calculation
-means testing -comparing a target -do not have sample statistics about the population
2-Sample T Test Sample Size Calculation
-means testing -comparing two sets of data
2-Sample Variance Test Sample Size Calculation
-variance testing -comparing variance from two sets of data
1- Sample Variance Test Sample Size Calculation
-variance testing -comparing variance of one data set to a target
1-Sample Proportion Test Sample Size Calculation
-proportion testing (rate x, per y) -comparing rate from one data set to a target
2-Sample Proportion Same Size Calculation
-proportion testing (rate x, per y) -comparing rate from two data sets
Analysis of Variance (ANOVA) Sample Size Calculation
-means testing -more than 2 sets of data -only one factor for x
Design of Experiment (DOE) Sample Size Calculation
-means testing -more than 2 sets of data -more than one factor for x
