• 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?
• Are they descriptive or inferential data, and
  what is the difference between these?
• (Note If you do not have a job where measures
  are available to you, ask someone you know for
  some examples,
• or conduct outside research on an interest of
  yours, or use personal measures.)

• www.uophelp.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.

  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. Please list, under each label, the
  variables in our data set that belong in each
  group..

  spend (utility costs each month, food costs,
  business supplies, etc.).
• Consider the measures and data you use (in either
  your personal or job activities).

  is simply an extension of what we covered last
  week.
• Just as we had 3 versions of the t-test (1
  sample, 2 sample (with and without equal
  variance), and paired
• we have several versions of ANOVA single
  factor, factorial (called 2-factor with
  replication in Excel), and within-
• subjects (2-factor without replication in Excel).
  What examples (professional, personal, social)
  can you provide on when we might use each type?
• What would be the appropriate hypotheses
  statements for each example?
