326 cases in which the defendant was convicted of murder:

(a) Use these data to make a two-way table of the defendant’s race (white or black) versus the death penalty (yes or no).

(b) Show that Simpson’s paradox holds: a higher percent of white defendants are sentenced to death overall, but for both black and white victims a higher percent of black defendants are sentenced to death.

(c) Use the data to explain why the paradox holds in the language that a judge could understand.

Part (a) Step 2: Concept

Data concerning two categorical variables are organized in a two-way table of counts. Two-way tables are frequently used to summarize vast volumes of data by categorizing outcomes.

Part (a) Step 3: Explanation

We create a two-way table comparing the defendant's race (white or black) vs. the death penalty (yes or no) using the data provided, as shown below. A two-way table is generated as a result.
