3: Numerical Summaries of Data — Read

From LibreTexts, under not declared, as the source states it; its equations are written in TeX, which the PDF shows typeset. This page at LibreTexts.

3.1: Measures of Center
In this section, we discuss how to measure the center of the data, or in other words how to define what is a typical observation in the data set.
3.2: Parameter and Statistic
In this section, we discuss the terminology associated with using samples to learn more about populations.
3.3: Measures of Variation
In this section, we discuss the measures of variation or spread that describe how much data varies from the center.
3.4: Interpreting the Mean and Standard Deviation
In this section, we discuss how to get an idea about the data distribution from the measures of the center and variation.
3.5: Measures of Relative Standing
In this section, we discuss the measures of relative standing that allow us to rank each observation in the data set.
3.6: Five-Number Summaries and Boxplots
In this section, we discuss how to figure out the shape of the distribution and the outliers using alternative numerical summaries.
