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? Are they
descriptive or inferential data, and what is the
difference between these?

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. An
example of a subjective probability is Cops
usually do not patrol this road, so I can get
away with speeding. An empirical probability
example is

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. For example, descriptive
statistics such as means can only be done on
interval or ratio level data.

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.)

4-1/Confidence Intervals Many people do not
like or trust single point estimates for
things they need measured. Looking back at the
data examples you have provided in the previous
discussion questions on this issue, how might
adding confidence intervals help managers accept
the results better? Why? Ask a manger in your
organization if they would prefer a single point
estimate or a range for important measures, and
why?

explained by their pay grade, appraisal rating,
education level, etc. What variables might
explain or predict an outcome in your department
or life? If you generated a regression equation,
how would you interpret it and the residuals from
it?
