Chapter 5 Exploring Data Analysis: Univariate Statistics

PDS video 6 does an excellent job of discussing univariate statistics, also known as descriptive statistics. This chapter will provide some additional help along with methods in R/RStudio to easily gather univariate statistics.

In the last chapter, we saw how to graph a single variable. With these graphs, we can get a sense of all three aspects of a variable discussed in the video.

• Center—also known as measures of central tendency
• Spread—also known as measures od dispersion such as range and interquartile range standard deviation
• Shape—also known as skewness

There is also a link to an excellent OpenStax statistics textbook with clear explanations of each of these three ideas. Links are above.
