• 1. For assistance with these calculations, see the
   Recommended Resources for Week One. Measurement i
  ssues. Data, even numerically code variables, can 
  be one of 4 levels  nominal, ordinal, interval, o
  r 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 inte
  rval or ratio level data. Please list, under each 
  label, the variables in our data set that belong i
  n each group..
• 2. The first step in analyzing data sets is to fin
  d some summary descriptive statistics for key vari
  ables. For salary, compa, age, Performance Rating,
   and Service find the mean and standard deviation

• Part One Multiple Testing
• Read Lecture Seven. The lectures from last week
  and Lecture Seven discuss issues around using a
  single test versus multiple uses of the same
  tests to answer questions about mean equality
  between groups. This suggests that we need to
  masteror at least understanda number of
  statistical tests. Why cant we just master a
  single statistical testsuch as the t-testand
  use it in situations calling for mean equality
  decisions? (This should be started on Day 1.)

• Part One Correlation
• Read Lecture Ten. Lecture Ten introduces the idea
  that different variables may move
  togethersometimes due to causation and at other
  times due to an unknown influence. An example
  involves the perfect (1.0) correlation between
  annual number of rum barrels imported into the
  New England region of the U.S. between the years
  1790 and 1820 and the number of churches built
  each of those years (citation lost).

• Question 1.  Compared to the ANOVA test, Chi
  Square procedures are not powerful (able to
  detect small differences).
