Static Method: `out =` USArrests `()` ¶

  Violent Crime Rates by US State

  #### Description ¶

  This data set contains statistics, in arrests per 100,000 residents for assault, murder, and rape in each of the 50 US states in 1973. Also given is the percent of the population living in urban areas.

  #### Format ¶

  `State`

    State name.

  `Murder`

    Murder arrests (per 100,000).

  `Assault`

    Assault arrests (per 100,000).

  `UrbanPop`

    Percent urban population.

  `Rape`

    Rape arrests (per 100,000).

  #### Note ¶

  `USArrests` contains the data as in McNeil’s monograph. For the `UrbanPop` percentages, a review of the table (No. 21) in the Statistical Abstracts 1975 reveals a transcription error for Maryland (and that McNeil used the same “round to even” rule), as found by Daniel S Coven (Arizona).

  See the example below on how to correct the error and improve accuracy for the ‘<n>.5’ percentages.
