Introduction to Statistics Unit 1 Milestone
Jenae is able to purchase a different brand of
coffee for half the price from a new supplier.
She anticipated that her co-workers would
object to switching to the new brand, as they
were really partial to the coffee they have been
drinking so far. Indeed, when offered a taste
test of the old brand versus the new brand, her
co-workers unanimously rejected the new
brand.
Jenae's boss, Steven, pointed out that this
result was most likely due to the fact that the
taste test was not ________.
controlled
# blinded
â— randomized
â— replicated
RATIONALE
Since they didn't keep the participants
unaware of what brand they were tasting, this
could influence the findings. So, the rejection
of the new brand was likely due to not
blinding them from what brand they were
drinking.
