Rounding and Other Considerations
Although values reported in the tables are generally rounded to one decimal place (e.g., 76.5 percent), values reported in each indicator are rounded to whole numbers (with any value of 0.5 or above rounded to the next highest whole number). Due to rounding, cumulative percentages may sometimes equal 99 or 101 percent, rather than 100.
In accordance with the recently revised NCES Statistical Standards, many tables in this website use a series of symbols to alert the reader to special statistical notes. These symbols, and their meaning, are as follows:
| — |
Not available.
Data were not collected or not reported.
|
| † |
Not applicable.
Category does not exist.
|
| # |
Rounds to zero.
The estimate rounds to zero.
|
| ! |
Interpret data with caution.
Estimates are unstable.
|
| ‡ |
Reporting standards not met.
Did not meet reporting standards. |
| * |
p <.05
Significance level.1
|
1The chance that the difference found between two estimates when no real difference exists is less than 5 out of 100.
