ISM-5150 Tableau Activity Version 1.0
Tableau Police Killings 2013-2020+
In this exercise you are playing the role of an analyst at one of the major news organizations in the United States.
Today there was another police killing/shooting and your boss needs detailed information on police killing from 2013 through 2020. This MUST be accurate as it will be used by the news reporters in their articles/news casts. Retractions are not acceptable!
Instructions: Just like you did in the Tableau Lab example this week, use the data file, “Killings by Police.xlsx” (found along with this assignment in Canvas) to answer the following questions.
10 Questions, 10 points each
Exercise #1
Using “for lines” chart, what state shows the highest number of police killings? What was the amount?
Hint: Drag “2013-2020 Police Killings (Count)” to Rows, drag “Date of Incident” to Columns. You now have a screen that looks like this:
Something isn’t right! Why is there a big drop-off in 2021? If you look at the data in the Excel file, you’ll see that there are only a few months of data in 2021, and since you’re being asked for data from 2013 through 2020, you need to filter out 2021.
Hover over YEAR (Date….) in the columns area. On the right side, click the dropdown arrow, go to filter and uncheck 2021. Apply and say OK. You will now see you line chart more level and 2021 is gone.
But we’re looking for states, so drag States to Columns. Note the chart changes to a bar chart automatically. Click the
button to change the orientation, then click the sort button
to sort from high to low.
If you’re showing individual years, drag State on top of “Date of Incident”.
If you now drag “2013-2020 Police Killings (Count)” to the Label box, you’ll get the values for each state.
