For this in-class assessment, you should be able to understand the following concepts. You should be able to compute them for a small dataset or use R commands to produce them from a larger dataset:

  • mean
  • median
  • quantiles (quartiles, deciles, ventiles, and percentiles)
  • variance (var)
  • standard deviation (sd)

You should also be able to read the output of the function reg_table and and estimate the standard deviation of a variable.
