Graphical Data Analysis Assignment 1
NOTE: This assignment contributes to your assessment for this course. As a result, you are
required to do the work ENTIRELY ONYOUR OWN. This means you may not obtain help
from other students. For this assignment, and for following assignments, please hand in
both text and graphics as part of your answer. The graphics you hand in should be
RELEVANT: that is DO NOT HAND IN EVERY GRAPHIC YOU PRODUCE IN THE PROCESS OF
WORKING THROUGH THE ASSIGNMENT. Marks will be deducted if you hand in irrelevant
graphics, and if your graphics are not sufficiently adorned with explanatory titles and axis
labels and so on. The text part of your answer should be in the form of a report: it is not
sufficient to merely annotate the graphics you produce. The text part of your report must be
CONCISE and TO THE POINT: answers that are too lengthy may also be penalized.
NOTE: There is a 4 (FOUR) page limit on this assignment, including text and all graphics. No
pages beyond the fourth will be read.
Task:
The heights in inches of the singers in the New York Choral Society in 1979 are contained in
a list called singers with components soprano.1, soprano.2, alto.1, alto.2, tenor.1, tenor.2,
bass.1 and bass.2.
These components are listed in order of decreasing pitch. The first four components are
female voices and the last four male. Describe and compare the height distributions, with
particular reference to what factors appear to be important in describing height.
Note: The data is contained in an R object named singers. This dataset is part of the
classdata library that can be downloaded from the class Wattle page.
