Section 2.1 Student Learning Objectives

In this chapter we deal with issues associated with the data that is obtained from a sample. The variability associated with this data is emphasized and critical thinking about validity of the data encouraged. A method for the introduction of data from an external source into R is proposed and the data types used by R for storage are described. By the end of this chapter, the student should be able to:

🔗

Recognize potential difficulties with sampled data.
🔗

🔗
Import data into R.
🔗

🔗
Organize your work in R-scripts.
🔗

🔗
Create and interpret frequency tables.
