I am trying to do a few tests in Minitab and I don't understand why they are not working out.
First, my data in minitab has several columns: Class Name Gender Height Age
, where
Class
has two values {A,B};Name
is the name of the students;Gender
is Female or Not female;Age
is the age of the student.
My questions I have to answer are as follows: Is the height of Class A larger than Class B?
My understanding of the question I should be a 2 sample t-test of the differences of the Height of Class A - Class B
However, every time I try to do a two sample t-test it just compares class with height, which is silly and doesn't workout.
How Do I get Minitab to test Class A's height against Class B's height?
Ps. If I am incorrect in the correct hypothesis testing method, please let me know.
