Problem set 4

Due by 11:59 PM on Tuesday, February 16, 2021


You must submit all assignments as a PDF document. Answer all questions carefully and neatly. Use section headings to distinguish what question you are answering. Be neat. If the question involves a graph, copy/paste the graph into your document and make sure the graph has a title.

Task 1: Crime in your country

Read about crime in the country you’ve been following, and look for either the biggest crime-related issue or an issue that seems unique or particular to your country. Give me a paragraph summary of that issue, including what the issue entails, how the state/public has responded to it, and if there are any controversies surrounding it. Include at least one link for reference.


Task 2: Crime data

Download this survey data on crime victimization experiences and perspectives from 8 countries in Latin America.

  1. Using either a plot or table of your choosing, report: 1) the proportion of respondents saying they have been the victims of crime; 2) the proportion who say they know that murders have occurred in their neighborhood; across all of the countries in the sample. Which countries are highest on these rates? Which are lowest? Is there a country that is high in one area but low in the other, or do victimization and murder rates largely move together?

  2. Using the table below, speculate on what you think the relationship between 3 pairs of variables might look like. Feel free to get creative about what variables you put together. 1 For each pair of variables, provide what you expect the relationship to look like, and justification (short).

  3. Plot the relationship and include a trend line2 (note that in order to see the relationship between some variables, you might need to use a pivot table first to take averages). Describe the relationship; is the result what you expected? If not, why do you think that might be?

  1. Silly example: taller people have a broader field of vision (they can see over stuff), therefore they should observe more crime than shorter people. So, as height increases, so does perception that crime is a problem.↩︎

  2. Trend line might not be appropriate in all cases, or make the plot look ugly. Handle with care!↩︎
