Accessing and Investigating Population Data 2: State Population Projections
Discipline
Mathematics
5, 6, 7
Professional Commentary

Students visit the United States Census Bureau website to investigate projections of the total population of states from 1995-2025. Using the provided data, students analyze statistics from five states of their choice, develop specific research questions using the data, and create three graphs to compare and contrast the information. Activity sheets are included. Internet extensions and links to background information are also provided. (author/sw)

Benchmarks (5–7)
A.
Read, create and use line graphs, histograms, circle graphs, box-and-whisker plots, stem-and-leaf plots, and other representations when appropriate.
B.
Interpret data by looking for patterns and relationships, draw and justify conclusions, and answer related questions.
E.
Collect, organize, display and interpret data for a specific purpose or need.
1.
Read, construct and interpret frequency tables, circle graphs and line graphs.
2.
Select and use a graph that is appropriate for the type of data to be displayed; e.g., numerical vs. categorical data, discrete vs. continuous data.
1.
Read, construct and interpret line graphs, circle graphs and histograms.
2.
Select, create and use graphical representations that are appropriate for the type of data collected.
5.
Describe the frequency distribution of a set of data, as shown in a histogram or frequency table, by general appearance or shape; e.g., number of modes, middle of data and level of symmetry, outliers.
6.
Make logical inferences from statistical data.
1.
Read, create and interpret box-and-whisker plots, stem-and-leaf plots, and other types of graphs, when appropriate.
2.
Analyze how decisions about graphing affect the graphical representation; e.g., scale, size of classes in a histogram, number of categories in a circle graph.
Principles and Standards for School Mathematics
Data Analysis and Probability Standard
Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them
Expectations (6–8)
formulate questions, design studies, and collect data about a characteristic shared by two populations or different characteristics within one population;
select, create, and use appropriate graphical representations of data, including histograms, box plots, and scatterplots.
Develop and evaluate inferences and predictions that are based on data
Expectations (3–5)
propose and justify conclusions and predictions that are based on data and design studies to further investigate the conclusions or predictions.
Expectations (6–8)
formulate questions, design studies, and collect data about a characteristic shared by two populations or different characteristics within one population;
