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. Please list, under

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.)

(more than two) data samples at the same time. We
will continue to use the data and assignment file

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.

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).

between and among the different variables. The
first question this week looks at correlations
and the creation of a correlation table for our

variables listed in a regression analysis.
Question 2. A correlation of .90 and above is
generally considered too strong to be of any
practical significance. Question 3. A p-value of

confidence intervals, the width of the interval
depends only on the variation within the data
