Explain any data inconsistencies that you found in your data files. Provide examples. Did you find any missing data? Did you find any typos or strange symbols? How did you handle them? What corrections did you make? Did you find any outliers (extremely large or extremely small values)? What method did you use to identify which values to consider outliers? Hint: the Empirical Rule can be useful to identify outliers. (refer to Chapter 3)
