For this assignment, you need to construct two graphs:
1) Graph A: Plot population (in millions) by year.
2) Graph B: Plot both the average annual increase (as bars) and rate of growth (as a line) by year.
You may use Excel and/or the following sample templates for starting your graph: 1)Population by Year graph (Graph A), and 2) Rate of Growth/Population Increase by Year (Graph B). Refer to the World Population Table for raw data. Enter the raw data on each graph. Graph A will consist of points connected by a solid line. Graph B has two components: use non-solid bars to represent the average annual population increase of growth; use points superimposed over the bars and connected by a solid line to present the average annual rate of growth. For additional assistance in constructing graphs in Excel, please review the optional reading in the Background Reading.
Refer to your completed graphs to respond to the following (you may also need to do a bit of historical research to help you interpret the data.)
Graph A (Be sure to include the graph in your paper)
Describe the world’s population growth in terms of the trajectory that you plotted.
Identify key periods of change on the graph. To what do you attribute each change, that is, relate such changes to any critical world event(s) which might have brought about each change?
Graph B (Be sure to include the graph in your paper)
Describe the relationship between the line graph and the bar graph.
What are the major factors contributing to the relationships observed?
Consider the world population’s current growth rate is 1.17%. At this rate, how many years would it take to double the size of the world’s population?
Case Assignment Expectations
Length: Case assignments should be 3-8 pages (750-2000 words) in length, excluding references.
References: At least two references must be included from academic sources (e.g. peer-reviewed journal articles). Required readings are included. Quoted material should not exceed 10% of the total paper (since the focus of these assignments is critical thinking). Use your own words and build on the ideas of others. When material is copied verbatim from external sources, it MUST be enclosed in quotes. The references should be cited within the text and also listed at the end of the assignment in the References section (APA format recommended).
Organization: Subheadings should be used to organize your paper according to question
Format: APA format is recommended for this assignment. See Syllabus page for more information on APA format.
Grammar and Spelling: While no points are deducted, assignments are expected to adhere to standards guidelines of grammar, spelling, punctuation, and sentence syntax. Points may be deducted if grammar and spelling impact clarity.
The following items will be assessed in particular:
Achievement of learning objectives for case assignment
Relevance (e.g. all content is connected to the question)
Precision (e.g. specific question is addressed. Statements, facts, and statistics are specific and accurate).
Depth of discussion (e.g. present and integrate points that lead to deeper issues)
Breadth (e.g. multiple perspectives and references, multiple issues/factors considered)
Evidence (e.g. points are well-supported with facts, statistics and references)
Logic (e.g. presented discussion makes sense, conclusions are logically supported by premises, statements, or factual information)
Clarity (e.g. writing is concise, understandable, and contains sufficient detail or examples)
Objectivity (e.g. avoid use of first person and subjective bias)
