Transcranial magnetic stimulation (TMS) is a non-invasive neurostimulation
procedure, involving a changing magnetic field that causes electric current
to flow in a target brain region. TMS has shown potential benefits to
learning and memory.
For the following questions, you will conduct a repeated measures t-test to
determine whether students memorized more vocabulary words while
undergoing TMS stimulation (experimental condition) versus "sham" TMS
(placebo condition), using a 2-tailed test with a = 0.05.
Maintain at least two decimal places. Also report the 95% CI for the mean
difference.
Use the following data table to compute your answers:
