BUS 308 Week 1 DQ 1 Language FOR MORE CLASSES
VISIT www.bus308outlet.com   Discussion
1-1/Language Numbers and measurements are the
language of business. Organizations look at
results in many ways expenses, quality levels,
efficiencies, time, costs, etc. What measures
does your department keep track of?

BUS 308 Week 1 DQ 1 Performance Report (Ash
Course) FOR MORE CLASSES VISIT
www.bus308outlet.com     You are the manager at
a company and are asked to present a report on
the year-to-date performance of your division.
What type of statistical information would you
include in your report? In particular, which
descriptive statistics (mean, median, standard
deviation, etc.) do you think would best
represent the main aspects of the performance of
your division? What types of graphical
presentation (histogram, dot plot, stem-and-leaf,
bar chart, etc.) would you include? Explain your
reasoning

BUS 308 Week 1 DQ 2 Probability FOR MORE
CLASSES VISIT www.bus308outlet.com   Things vary
in life virtually nothing (except physical
standards such as the speed of light) we interact
with is constant over time. Much of this
variation follows somewhat predictable patterns
that can be examined using probability.

BUS 308 Week 1 DQ 2 The Empirical Rule vs.
Chebyshev Theorem (Ash Course) FOR MORE CLASSES
VISIT www.bus308outlet.com     The Empirical
Rule vs. Chebyshevs TheoremDiscuss how the
Empirical Rule works and how it relates to the
bell curve as illustrated in Figure 3.14 (a).
Then, explain Chebyshevs Theorem and how it is
different from the Empirical Rule. Give a
specific example of a population with which the
Empirical Rule might be most effective and one
with which Chebyshevs Theorem might be most
effective. Respond to at least two of your
classmates postings.

BUS 308 Week 1 Problem Set FOR MORE CLASSES
VISIT www.bus308outlet.com   1. For assistance
with these calculations, see the Recommended
Resources for Week One. Measurement issues.
Data, even numerically code variables, can be
one of 4 levels nominal, ordinal, interval, or
ratio. It is important to identify which level a
variable is, as this impacts the kind of analysis
we can do with the data.

BUS 308 Week 2 DQ 1 Hypotheses FOR MORE CLASSES
VISIT www.bus308outlet.com     Discussion
2-1/Hypotheses What is a hypothesis test? Why do
we need to use them to make decisions about
relating sample results to the population why
cant we just make our decisions by the sample
value?
13
BUS 308 Week 2 DQ 1 Relative Frequency (Ash
Course) FOR MORE CLASSES VISIT
www.bus308outlet.com     Relative Frequency.
Conceptually we would expect the probability of
newborn males and females to be the same.
However, census reports indicate that the ratios
of males and females in various countries do not
conform to the theoretical prediction. What do
you think accounts for this variation? Can you
think of other cases where the expected
probabilities do not quite agree with the
empirical values?
14
BUS 308 Week 2 DQ 2 Applications for Probability
(Ash Course) FOR MORE CLASSES VISIT
www.bus308outlet.com     Applications for
Probability. In what situations might you use
probability as a manager to approach

or possible pitfalls to avoid in using
probability in business?
15
BUS 308 Week 2 DQ 2 Variation FOR MORE CLASSES
VISIT www.bus308outlet.com     Variation exists
in virtually all parts of our lives. We often
see variation in results in what we spend
(utility costs each month, food costs, business
supplies, etc.). Consider the measures and data
you use (in either your personal or job
activities). When are differences (between one
time period and another, between different
production lines, etc.) between average or actual
results important?
