Assignment 12 Due Monday, Day 19, May 7
You can do all your printouts at once on the same page, if you
like. But: Be sure to write the things asked for.
-
A. (beginning Ch.2) Work pp. 12-13, using
Sample.sav. Insert a new text label (see notes above) explaining
that this is for Day = 1 people only (who are they?? MWF or TTH?). Hand
in the printout of your work, including label.
-
B. (after Ch.2) Enter Practice Data Set 2, p. 108. Save it as Pracdata2.sav.
-
a) Use Transform>Recode (like p. 15-16) to
Make a new variable, Longterm, which codes 11 or more years of service
to 3, 6 to 10 years to 2, and 5 or fewer to 1. Label the values in
Longterm as 3=Long, 2= Med, 1=Short.
-
b) Use Transform Compute (like p. 14) toMake
another new variable Seniorty (only 8 letters allowed) which combines years
of service with education as Seniorty = YOS + 2*Educ; that is, a year more
education is "worth" the same as 2 years of service.
Save
the data
file.
-
c) Find the means of Seniorty and Longterm (You can do them both
at once--just move both variables into the box. You get a lot of other
stuff too.) Print this table out, circling the means. Write
on your paper whether the mean is a sensible measure to apply to Seniority.
To Longterm. Hand in.
-
C. (after sec. 3.1) Practice Data Set 1 should be in Class
Materials/CS103/SPSS Stuff/Pracdata1.sav
-
a) Do Practice Exercise, p.20 top.
-
b) Find the median, 1st and 3rd quartiles, and the maximum and minimum
of the math skill scores. On the printout, draw, by hand, a boxplot.
Hand
in.
