Graph Interpretation

This recognition and recall practice is based on a very simple graph in California Youth Authority's slide presentation on changing characteristics of youthful offenders.

Click on any of the question numbers for jeanne's lecture notes on these questions.

  1. Name the variable or variables in this graph, and tell whether they are measured as nominal, ordinal, or interval.

  2. How did the CYA measure ethnicity? Is the answer readily apparent?

  3. Could the population comparison of men and women over time, in Nan Chico's animated graph, have been shown in a graph like the one CYA used? Nan Chico's Starters

  4. Could we use the type of graph the CYA used to show the relationship between black and white male homicide? Nan Chico's Starters Scroll down to last chart on page.

  5. How would the CYA graph look if you threw out some data and graphed African Americans and Hispanics together as against Caucasians, with the Other category still separate? Would this be justifiable statistically?
