2) The head of HR in a 50,000 person pharmaceutical company
wanted to determine if she should implement a work at home policy
for the company. First, she wanted some information. She asked the
data analyst to determine if marital status affected commuting
times. She assumed that married people lived farther away because
they were more likely to have children and be concerned about
school districts and communities. On the other hand, single people
would want to live close to work.
The HR analyst tasked with the job randomly selected 15
employees and found that marital status was related to
commute times, but surprisingly, it was in the opposite direction.
She found single people lived farther away than married people.
What error did the HR analyst make?
a)Recency bias
b)Stereotyping
c)Reverse causality
d)Sample not representative (too small)
3)Which error does the following represent?
A manager is evaluating two employees. The first employee has

employee.

c)Central tendency
d)Reverse causality
4) The following headline appeared in a recent article:
Brain Scans of Hoarders Reveal Why They Never
De-Clutter
To find out more about how the brains of hoarders might actually
differ from those of healthy adults—and potentially even those with
OCD—Tolin and his colleagues recruited 43 adults with a diagnosed
hoarding disorder, 31 with OCD, and 33 healthy adult controls to
undergo fMRI brain scans. Each subject was asked to bring in a
stack of miscellaneous, unsorted papers from their home, such as
newspaper and junk mail.
Subjects were asked to choose whether they wanted to keep a
displayed item.
Healthy controls chose to discard a mean of about 40 of the 50
items they brought. Those with OCD discarded about 37 items. But
those with a hoarding disorder discarded only about 29 of the 50
things they brought.
What error is the headline making?
a)Availability bias
b)Regression to the mean
c)Correlation is not causation
d)Central tendency
