The manager of an amusement park conducts a survey among the people visiting the park to learn their favorite rides. Out of 100 people randomly selected to complete
the survey, 25 people have chosen not to participate.
The manager's survey suffers from which of the following types of bias?
Selection bias
Nonresponse bias
Response bias
There is no bias in the way this survey is carried out.
RATIONALE
Since 25% of the people didn't respond to the survey, we would worry about nonresponse bias, which means those who didn't respond would produce a very different
outcome than those who did respond.
CONCEPT

Jenae changed the original coffee labels with plain white ones that had the flavor printed in bold black letters, and she placed them on the coffee pots for the week-long
experiment.
Jenae used an aspect of experimental design known as ________ when she created the labels to have the same appearance.
a control
replication
a treatment
randomization
RATIONALE
In an experiment, controls are when conditions are manipulated by the experimenter to keep conditions as consistent as possible. When Jenae makes the labels the same
the entire week, this is an example of a control.

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 ________.
replicated
randomized
controlled
blinded
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.
