This slide displays a simulation of an interactive map graphic. The query used is Grade 8, Reading, all jurisdictions and National Public, and the variable "Newspaper at home" All U.S. states and data jurisdictions are shown on the map. The animated cursor moves over Texas, Oklahoma, Kansas, Nebraska, South Dakota, and North Dakota revealing underlying data for each state.
The NAEP Data Explorer can produce interactive map graphics through statistical significance tests. This requires knowing how to check statistical significance, so review that lesson if necessary.
This slide displays the Select Criteris screen in Advanced mode. Already selected are Grade 8, Reading, and the variable "Newspaper at home". The cursor moves to select "Select All" under the "State/Jurisdiction" category. The cursor then moves to click the Choose Years button, which displays that page, and then the Format Table button, which displays that page. The cursor moves to click Go To Results. The resulting table is displayed. Finally, the cursor moves to click the Find Out button to display the Check Statistical Significance popup window.
To obtain a map graphic, make a query that includes at least two jurisdictions. Do not collapse categories and avoid percentile queries. NDE may fail to process such queries for the map. All other formatting is compatible, including cross-tabulation. Go to the results page, then open a statistical significance test.
In this animation the cursor moves to expand the "Jurisdiction" node in the Selections panel. The cursor then moves to select "Select All" and all jurisdictions are highlighted. The screen scrolls to the bottom and the cursor moves to point to the selected year 2003. The cursor moves to select "Show Graph" and then under the category "Variable", "Newspaper at home" selects "Yes" Finally, the screen scrolls to the top, the cursor moves to click the Compute button, a "Loading" popup appears momentarily, and the map graphic is constructed and displayed.
On the significance test window, first select two or more jurisdictions, then select only one year, and finally select Show Graph under Display Options. Do not select Show Detail. Select all other criteria normally. Click Compute.
This slide displays an animation of a typical map graphic. National Public is indicated as the focus. The cursor moves across Texas on the map and it is highlighted. Banner text updates with a comparison of Texas scores to those of National Public. The cursor clicks Texas and it becomes the focus for other comparisons. The cursor moves to New Mexico and its score is compared to Texas. The cursor then moves to point out the legend and then moves to a square labeled with a region. The South region is highlighted and its scores are compared to Texas. The cursor then moves to the square for Houston. A push pin symbol appears on the map and Houston scores are compared to Texas.
Mouse over any state to highlight it. Click any jurisdiction to make it the focal jurisdiction. Colors and dynamic messages compare other states with the focal jurisdiction. The legend at bottom explains how. For jurisdictions not shown, use the squares next to the map. Regions are displayed by color and borders. Urban districts, like Houston, are marked by push pins.
