Week 3: Descriptive Statistics and Summarizing Data

Agenda

• No homework / no quiz today. Next quiz will take place next Tuesday.
• Lecture on descriptive statistics and summarizing data. We will refresh our memory about measures of center, spread, and describing both continuous (scale) and categorical (nominal/ordinal) distributions.
  • Like last week, you may download an R script (which contains only the code chunks from the lecture) and follow along in RStudio by running line-by-line: week_3.R
• Hands-on lab to explore a dataset concerning housing-related data for Boston census tracts. You will use descriptive statistics and simple visual displays to summarize the distributions of several variables across the census tracts.
  • lab_3_blank.qmd
  • lab_3.pdf
