What is the correct tool to use in excel through tools>data analysis Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! You might try a box plot on each of the data sets.
-
You could run a t-test on the (before-after) data.
using Ho: u(difference) = 0
Ha: u(difference) is not zero.
--------------------------------
These data pairs are dependent because each
pair is a before/after measure for a person.
So, do not use a 2-sample t-test; do not ues
a 2-sample z-test.
