visit www.newtonhelp.com   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.)

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?

Four  This week we get to answer our equal pay
for equal work question by looking at
relationships between and among the different
variables. The first question this week looks at
