Last week, in Chapter 10 Exploratory Data Analysis, we practiced using plots
to explore data. While we are generating plots to explore data, we are not
always paying attention to the explanations of the plots themselves. We know
what variables we are using and we know (or at least think that we know) what
we expect to see.
When we are presenting our work to other people, they may have no experience
with the data whatsoever. They do not know what variables are contained in the
data, or what values those variables might assume.
To communicate with others, we need to use all facets of a graphic to educate
our audience, call attention to key details, and present the conclusions that
we have reached.
Our goal is to quickly bring our audience to the place where they can understand
what we are representing and to give them a basis for deciding whether or not
they agree with our conclusions.
Chapter 11 Communication introduces you to many of the fine adjustments
you can control in a graphic through the use of labels, annotations, scales,
themes, and layouts.
There are many features to explore here. As you have more opportunity in the
future you will spend much time reading through the documentation in the help
pane.
Assessment deadlines will be 11:59pm each Saturday.
All assessments are submitted to the Homework Folder inside your assigned
Google Drive folder.
There are no make-ups for missed assessments. Contact me before a deadline
if you have an issue meeting the deadline and we will find a mutually
agreeable solution.
