What is the relationship between One-Sample Test, Two-Sample Test, Analysis of Variance, and Regression? How do you decide on which test to perform?
Solutions
Expert Solution
These are all different test
one-sample t-test is used when there is only one variable and you want to compare the mean to a specific value
In Two-Sample Test , there are two independent variable, and you want to compare the difference in means between them
In Analysis of Variance or ANOVA , there are greater than or equal to 2 levels
and we compare the means among them
Ho: µ1 = µ2= ..µk
Ha: at least one mean is different
For regression, there is one independent variable and one dependent variable
we want to see how change in independent variable affect dependent variable
y^ =a+ b* x
