How Can you Use Statistics
An understanding of statistics is necessary in any job. The use of statistics can help provide answers to many questions. Please, post a question you think that statistics may help you answer and explain why statistics can help provide an accurate answer. Read several of your classmates’ postings. Do you agree that statistics are necessary to answer their questions? Is their question one that you would also like to have an answer to? Why or why not?

Looking at Statistics
The internet is host to a wealth of information and much of that information comes from raw data that have been collected or observed.
Many websites summarize such data using graphical methods discussed in this chapter.
Find a website related to your major that summarizes data and uses graphs, and share it with the class. Let us know how it relates to your major and why it is of interest to you.
