State Data Map

  • State Data Map

    Grade:

    Information can be represented in many ways, and this applet allows the user to represent data about the states using colors. The state with the highest data value is darkest; other states are shaded proportionally. Investigate any of the data provided—or enter data of your own!

    Instructions

    • Each state in the map below is shaded a percentage of color proportional to the largest data for any state.
      Using the Population data set, for example, California (population 33,871,648) is shaded at 100%, because it has the greatest population; but Colorado (population 4,301,261) is only shaded at 13%, because 4,301,261 ÷ 33,871,648 ≈ 0.13.
    • Choose a Data Set to view various state data. Alternatively, enter values for each state in the table; then, click Update Map to view the results.
    • The Clear Data button can be used to replace all state data with X's. An X indicates that there is no data entered for that state, and data for that state will not influence the mean or five-number summary. (By contrast, a data value of "0" will influence the measures of center.)
    • Click Hide Map Numbers to remove the data from the map. (The data will still be displayed in the table, however.)
    • Change the color of the shading by selecting a different color from the Map Color pull‑down menu.
