BUS 352 Grand Canyon Module 8 Discussion 1
A market researcher is interested in knowing the type of training
that works best for DVD users. Thirty consumers are randomly selected from a
population of known DVD owners (i.e., users). Ten users are trained by giving
them the DVD user’s manual and allowing them to read it. Another 10 users are
trained from a 30 minute DVD user training video. Another 10 users are trained
from a selfpaced computer tutorial. The users are then timed in their ability
to setup and program the DVD by performing a series of operations. Which
statistical analysis technique should be used? What is the null hypothesis? Can
the market researcher get an answer? Why or why not?
