  can be one of 4 levels  nominal, ordinal, interva

•    
• 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.)

• www.newtonhelp.com
•     During this week, we will look at ways of
  testing multiple (more than two) data samples at
  the same time.
•  
• We will continue to use the data and assignment
  file that we opened in Week 2, we just move on to
  the Week 3 tab.
•  
• The first question asks us to determine if the
  average compa-ratio is equal across 10K salary
  groups (20 29K. 30 39K, etc.).  The second
  question asks us to identify which of the salary
  groups have different averages.  The final
  question asks us to interpret the new information
  presented in the lecture and assignment how does
  the new information we analyzed help us answer
  our equal pay for equal work question.

•      
• 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). Discuss this
  correlation What does it tell us? Does rum
  drinking cause church building? Does church
  building cause rum drinking? Or what else could
  it tell us? If this correlation shows a cause and
  effect relationship, what drives what? If not,
  why does it exist? What could this correlation be
  used for? (This should be started on Day 1.)

• Question 1.  Compared to the ANOVA test, Chi
  Square procedures are not powerful (able to
  detect small differences).
• Question 2.  In confidence intervals, the width
  of the interval depends only on the variation
  within the data set.
• Question 3.  The percent confidence interval is
  the range having the percent probability of
  containing the actual population parameter.
• Question 4.  The Chi Square test can be performed
  on categorical (nominal) level data.
