29 May Explain the differences among histograms, relative-frequency histograms, bar graphs, circle graphs, time-series graphs, Pareto charts, and stem-and-leaf displays
Module 2: Organizing Data Assignment
1. In your own words, explain the differences among histograms, relative-frequency histograms, bar graphs, circle graphs, time-series graphs, Pareto charts, and stem-and-leaf displays. If you have nominal data, which graphic displays might be useful? What if you have ordinal, interval, or ratio data?
2. What do we mean when we say a histogram is skewed to the left? To the right? What is a bimodal histogram? Discuss the following statement: “A bimodal histogram usually results if we draw a sample from two populations at once.” Suppose you took a sample of weights of college football players, and with this sample, you included the weights of cheerleaders. Do you think a histogram made from the combined weights would be bimodal? Explain.
3. Discuss the statement that stem-and-leaf displays are quick and easy to construct. How can we use a stem-and-leaf display to make the construction of a frequency table easier? How does a stem-and-leaf display help you spot extreme values quickly?

As doctoral students, your assignments are expected to follow the principles of high-quality scientific standards and promote knowledge and understanding in the field of criminal justice. You should apply a rigorous and critical assessment of a body of theory and empirical research, articulating what is known about the phenomenon and ways to advance research about the topic under review. Research syntheses should identify significant variables, a systematic and reproducible search strategy, and a clear framework for studies included in the larger analysis.
Assignments may be written in first person (“I”).
All assignments should be clearly and concisely written, with technical material set off. Please do not use jargon, slang, idioms, colloquialisms, or bureaucratese. Use acronyms sparingly and spell them out the first time you use them. Please do not construct acronyms from phrases you repeat frequently in the text.

I expect all papers to be in the latest APA edition, properly cited, and additional resources used besides classroom textbooks.
