1. [12 pts] A database of passwords partitioned these into 10 categories. These categories appear in the variable category. The time to crack the password by online guessing varied so much that different units of time were used. The variable time_unit which contains these units is an ordinal variable describing how long it takes to guess the password. The label NA in the plots indicates missing values.

Each question below presents two visualizations for the data in a variable. a) Describe the difference between the two visualizations, choose one of the visualizations (I. or II.), and indicate why you chose it; b) Describe the data using the graph that you selected. If appropriate discuss the data in terms of shape and departures from shape. c) Using the information from the graph indicate how you would summarize location (mean, median, or neither) and spread (standard deviation, IQR, or neither). Give reasons for the summaries that you chose or for choosing neither summary.
