# Assessment C

For the third in-class assessment, you should be able to:

• identify and describe the difference between numeric and character variables
• accurately produce a full data dictionary for a dataset
• understand what makes a character variable a categorical one
• understand the naming rules for variables (no capital letters, no arbitrary numbers, no spaces or other special characters, underscores in place of spaces )
• be able to write the ggplot2 command to build a simple scatter plot (geom_point) from a data frame

Remember that, as was the case with Assessment B, you will be expected to produce R code not just select the correct answers from a multiple choice list of options.
