Monday: Primarily a conceptual lecture covering data models and their purpose followed by tabular model and tidy data, with emphasis on understanding the variables and values in a data set. Conclude with constructing `pandas` data frames. Tuesday: Problem day, building on `pandas` data frame construction and perhaps `pandas` tutorial, and getting to column projection and simple row selection. Wednesday: More complex row and column and combinations. Procedural access through iteration. Friday: Tabular formats and considerations, wrap any loose ends on chapter 7 coverage.
