Table 13-10-0835-01 Food insecurity by selected demographic character- istics. (a) Choose one year. Graph this column of data using an appropriate type of graph. • The graph must be made by hand (i.e., not using Excel) and properly labelled. See the INSTRUCTIONS for details. (b) Summarize the data you graphed in part (a) in a coherent paragraph (about 250 words). • Begin the paragraph explaining briefly why it is useful to know about food insecurity across different demographic groups. Consider this from a government perspective and a common citizen's (such as yourself) perspective. • Consider appropriate numerical summaries. • Comment on trends you notice and what may have caused the trend(s). This will likely require you to think about recent news, etc. (c) Include all calculations you did for part (b) either before the paragraph or after the paragraph. • A severe penalty will be applied if calculations are not provided.
