For a bit of in-class python coding, we'll fill out a Python script to read in a comma-delimited file, and calculate, for each column:

• Number of non-missing values
• Mean
• Median
• SD

Here are the relevant files:

• data.csv — the data file to consider
• stats.py — the script to be filled in
• stats2.py — partly-filled version: just fill in the functions to calculate the statistics
• test_stats.py — unit tests for functions in stats.py

Also relevant:

• create_example_data.py — the Python script I wrote to generate the data.csv file.
• solns_DONT_PEEK.py — my solutions (don't look at this until later)
