There is no one correct way to write. But there are things you can do
that tend to make it difficult for a reader to absorb the ideas you
are writing about, or make it easier for the reader. Thus, it is
important to focus on the reader, and the constraints and habits of
mind that most readers (even in the rarefied population of academics
who can understand the technical details of your work) bring to the
task of reading what you have written.  The goals for students in this
course are: to understand that writing requires an intellectual
investment similar to the investment that you put into other areas of
your research, from developing research questions, data collection,
and data analysis, to writing and testing algorithms, and formulating
and proving theorems; to understand ways of organizing your writing
that make it more likely that the reader will interpret and understand
your ideas in the way that you intend; and to gain experience writing
with these ideas in mind.  The course is most suitable for graduate
students in statistics who are engaged in a writing project (ADA
paper, journal article, thesis work, etc.).
