Discuss the relationship, if any, each of these variables have with the target variable. b. Which variables would you expect to make a significant appearance in any data classification model we work with?

28. Report on whether anomalous fields exist in this data set, based on your EDA, which fields these are, and what we should do about it. Identify at least one anomalous field or argue convincingly that there is none.

29. Report the mean, median, minimum and maximum for each of the numeric variables.
