The lecture covered part of section 1.1 in the book:

• What is statistics? The study of data.

• What is data? Data is tables.

• What are tables? Tables are rows and columns.

• What are rows? Rows are units, the subjects of inquiry.

• What are columns? Columns are variables, the characteristics of the units.

In class we came up with two little examples for data:

student over 21 hair color male/female
Bob no brown male
Sarah no black female
Jean yes brown female
student new worth height distance home
Kristin $2,000 5’5” 200 mi Jordan$1,000,000 6’0” 15 mi
