Hss2381 quantitative methods
Midterm review!
The midterm.
Is on Wednesday Nov 4
Today:
Go over what weve learned
Describe the midterm
The only formulae you will be given
t = (x  ) / SEM
t = D / [(n D2) (D)2)/(n1)]
Also will be given Z and t table
HSS2381C MORE SAMPLE MIDTERM QUESTIONS
The measurement level that classifies attributes, indicates magnitude, and has equal intervals between
values, but does not have a rational zero, is:
a. Nominal
b. Ordinal
c. Interval
d. Ratio
It is not meaningful to
